 # WebHost
 
+## Asset License
+
+The image files used in the page design were specifically designed for archipelago.gg and are **not** covered by the top
+level LICENSE.
+See individual LICENSE files in `./static/static/**`.
+
+You are only allowed to use them for personal use, testing and development.
+If the site is reachable over the internet, have a robots.txt in place (see `ASSET_RIGHTS` in `config.yaml`)
+and do not promote it publicly. Alternatively replace or remove the assets.
+
 ## Contribution Guidelines
-**Thank you for your interest in contributing to the Archipelago website!**  
-Much of the content on the website is generated automatically, but there are some things
-that need a personal touch. For those things, we rely on contributions from both the core
-team and the community. The current primary maintainer of the website is Farrak Kilhn.
-He may be found on Discord as `Farrak Kilhn#0418`, or on GitHub as `LegendaryLinux`.
 
-### Small Changes
-Little changes like adding a button or a couple new select elements are perfectly fine.
-Tweaks to style specific to a PR's content are also probably not a problem. For example, if
-you build a new page which needs two side by side tables, and you need to write a CSS file
-specific to your page, that is perfectly reasonable.
+Pages should preferably be rendered on the server side with Jinja. Features should work with noscript if feasible.
+Design changes have to fit the overall design.
 
-### Content Additions
-Once you develop a new feature or add new content the website, make a pull request. It will
-be reviewed by the community and there will probably be some discussion around it. Depending
-on the size of the feature, and if new styles are required, there may be an additional step
-before the PR is accepted wherein Farrak works with the designer to implement styles.
+Introduction of JS dependencies should first be discussed on Discord or in a draft PR.
 
-### Restrictions on Style Changes
-A professional designer is paid to develop the styles and assets for the Archipelago website.
-In an effort to maintain a consistent look and feel, pull requests which *exclusively*
-change site styles are rejected. Please note this applies to code which changes the overall
-look and feel of the site, not to small tweaks to CSS for your custom page. The intention
-behind these restrictions is to maintain a curated feel for the design of the site. If
-any PR affects the overall feel of the site but includes additive changes, there will
-likely be a conversation about how to implement those changes without compromising the
-curated site style. It is therefore worth noting there are a couple files which, if
-changed in your pull request, will cause it to draw additional scrutiny.
-
-These closely guarded files are:
-- `globalStyles.css`
-- `islandFooter.css`
-- `landing.css`
-- `markdown.css`
-- `tooltip.css`
-
-### Site Themes
-There are several themes available for game pages. It is possible to request a new theme in
-the `#art-and-design` channel on Discord. Because themes are created by the designer, they
-are not free, and take some time to create. Farrak works closely with the designer to implement
-these themes, and pays for the assets out of pocket. Therefore, only a couple themes per year
-are added. If a proposed theme seems like a cool idea and the community likes it, there is a
-good chance it will become a reality.
+See also [docs/style.md](/docs/style.md) for the style guide.

-# apworld Specification
+# APWorld Specification
 
 Archipelago depends on worlds to provide game-specific details like items, locations and output generation.
-Those are located in the `worlds/` folder (source) or `<install dir>/lib/worlds/` (when installed).
+These are called "APWorlds".
+They are located in the `worlds/` folder (source) or `<install dir>/lib/worlds/` (when installed).
 See [world api.md](world%20api.md) for details.
+APWorlds can either be a folder, or they can be packaged as an .apworld file.
 
-apworld provides a way to package and ship a world that is not part of the main distribution by placing a `*.apworld`
-file into the worlds folder.
+## .apworld File Format
 
-**Warning:** apworlds have to be all lower case, otherwise they raise a bogus Exception when trying to import in frozen python 3.10+!
+The `.apworld` file format provides a way to package and ship an APWorld that is not part of the main distribution

-
-## File Format

+`.apworld` files are zip archives, all lower case, with the file ending `.apworld`.
 The zip has to contain a folder with the same name as the zip, case-sensitive, that contains what would normally be in
 the world's folder in `worlds/`. I.e. `worlds/ror2.apworld` containing `ror2/__init__.py`.
 
+**Warning:** `.apworld` files have to be all lower case,
+otherwise they raise a bogus Exception when trying to import in frozen python 3.10+!
 
 ## Metadata
 
-No metadata is specified yet.
+Metadata about the APWorld is defined in an `archipelago.json` file.
 
+If the APWorld is a folder, the only required field is "game":
+```json
+{
+  "game": "Game Name"
+}
+```
 
-## Extra Data
+There are also the following optional fields:
+* `minimum_ap_version` and `maximum_ap_version` - which if present will each be compared against the current
+  Archipelago version respectively to filter those files from being loaded.
+* `world_version` - an arbitrary version for that world in order to only load the newest valid world.
+  An APWorld without a world_version is always treated as older than one with a version
+  (**Must** use exactly the format `"major.minor.build"`, e.g. `1.0.0`)
+* `authors` - a list of authors, to eventually be displayed in various user-facing places such as WebHost and
+  package managers. Should always be a list of strings.
 
-The zip can contain arbitrary files in addition what was specified above.
+If the APWorld is packaged as an `.apworld` zip file, it also needs to have `version` and `compatible_version`,
+which refer to the version of the APContainer packaging scheme defined in [Files.py](../worlds/Files.py).  
+These get automatically added to the `archipelago.json` of an .apworld if it is packaged using the 
+["Build APWorlds" launcher component](#build-apworlds-launcher-component),
+which is the correct way to package your `.apworld` as a world developer. Do not write these fields yourself.
 
+### "Build APWorlds" Launcher Component
+
+In the Archipelago Launcher, there is a "Build APWorlds" component that will package all world folders to `.apworld`,
+and add `archipelago.json` manifest files to them.  
+These .apworld files will be output to `build/apworlds` (relative to the Archipelago root directory).  
+The `archipelago.json` file in each .apworld will automatically include the appropriate
+`version` and `compatible_version`.  
+The component can also be called from the command line to allow for specifying a certain list of worlds to build.
+For example, running `Launcher.py "Build APWorlds" -- "Game Name"` will build only the game called `Game Name`.
+
+If a world folder has an `archipelago.json` in its root, any fields it contains will be carried over.  
+So, a world folder with an `archipelago.json` that looks like this:
+
+```json
+{
+    "game": "Game Name",
+    "minimum_ap_version": "0.6.4",
+    "world_version": "2.1.4",
+    "authors": ["NewSoupVi"]
+}
+```
+
+will be packaged into an `.apworld` with a manifest file inside of it that looks like this:
+
+```json
+{
+    "minimum_ap_version": "0.6.4",

+This is the recommended workflow for packaging your world to an `.apworld`.
+
+### .apignore Exclusions
+
+By default, any additional files inside of the world folder will be packaged into the resulting `.apworld` archive and
+can then be read by the world. However, if there are any other files that aren't needed in the resulting `.apworld`, you
+can automatically prevent the build component from including them by specifying them in a file called `.apignore` inside
+the root of the world folder.
+
+The `.apignore` file selects files in the same way as the `.gitignore` format with patterns separated by line describing
+which files to ignore. For example, an `.apignore` like this:
+
+```gitignore
+*.iso
+scripts/
+!scripts/needed.py
+```
+
+would ignore any `.iso` files and anything in the scripts folder except for `scripts/needed.py`.
+
+Some exclusions are made by default for all worlds such as `__pycache__` folders. These are listed in the
+`GLOBAL.apignore` file inside of the `data` directory.
 
 ## Caveats
 
-Imports from other files inside the apworld have to use relative imports. e.g. `from .options import MyGameOptions`
+Imports from other files inside the APWorld have to use relative imports. e.g. `from .options import MyGameOptions`

+### I've never added a game to Archipelago before. Should I start with the APWorld or the game client?
+
+Strictly speaking, this is a false dichotomy: we do *not* recommend doing 100% of client work before the APWorld,
+or 100% of APWorld work before the client. It's important to iterate on both parts and test them together.
+However, the early iterations tend to be very similar for most games,
+so the typical recommendation for first-time AP developers is:
+
+- Start with a proof-of-concept for [the game client](adding%20games.md#client)
+  - Figure out how to interface with the game. Whether that means "modding" the game, or patching a ROM file,
+    or developing a separate client program that edits the game's memory, or some other technique.
+  - Figure out how to give items and detect locations in the actual game. Not every item and location,
+    just one of each major type (e.g. opening a chest vs completing a sidequest) to prove all the items and locations
+    you want can actually be implemented.
+  - Figure out how to make a websocket connection to an AP server, possibly using a client library (see [Network Protocol](<network%20protocol.md>).
+    To make absolutely sure this part works, you may want to test the connection by generating a multiworld
+    with a different game, then making your client temporarily pretend to be that other game.
+- Next, make a "trivial" APWorld, i.e. an APWorld that always generates the same items and locations
+  - If you've never done this before, likely the fastest approach is to copy-paste [APQuest](<../worlds/apquest>), and read the many
+    comments in there until you understand how to edit the items and locations.
+- Then you can do your first "end-to-end test": generate a multiworld using your APWorld, [run a local server](<running%20from%20source.md>)
+  to host it, connect to that local server from your game client, actually check a location in the game,
+  and finally make sure the client successfully sent that location check to the AP server
+  as well as received an item from it.
+
+That's about where general recommendations end. What you should do next will depend entirely on your game
+(e.g. implement more items, write down logic rules, add client features, prototype a tracker, etc).
+If you're not sure, then this would be a good time to re-read [Adding Games](<adding%20games.md>), and [World API](<world%20api.md>).
+
+There are a few assumptions in this recommendation worth stating explicitly, namely:
+
+- If something you want to do is infeasible, you want to find out that it's infeasible as soon as possible, before
+  you write a bunch of code assuming it could be done. That's why we recommend starting with the game client.
+  - Getting an APWorld to generate whatever items/locations you want is always feasible, since items/locations are
+    little more than id numbers and name strings during generation.
+- You generally want to get to an "end-to-end playable" prototype quickly. On top of all the technical challenges these
+  docs describe, it's also important to check that a randomizer is *fun to play*, and figure out what features would be
+  essential for a public release.
+- A first-time world developer may or may not be deeply familiar with Archipelago, but they're almost certainly familiar
+  with the game they want to randomize. So judging whether your game client is working correctly might be significantly
+  easier than judging if your APWorld is working.

@@ -140,3 +183,58 @@ So when the game itself does not follow this assumption, the options are:
   - For connections, any logical regions will still need to be reachable through other, *repeatable* connections
   - For locations, this may require game changes to remove the vanilla item if it affects logic
 - Decide that resetting the save file is part of the game's logic, and warn players about that
+
+---
+
+### What are "local" vs "remote" items, and what are the pros and cons of each?
+
+First off, these terms can be misleading. Since the whole point of a multi-game multiworld randomizer is that some items
+are going to be placed in other slots (unless there's only one slot), the choice isn't really "local vs remote";
+it's "mixed local/remote vs all remote". You have to get "remote items" working to be an AP implementation at all, and
+it's often simpler to handle every item/location the same way, so you generally shouldn't worry about "local items"
+until you've finished more critical features.
+
+Next, "local" and "remote" items confusingly refer to multiple concepts, so it's important to clearly separate them:
+
+- Whether an item happens to get placed in the same slot it originates from, or a different slot. I'll call these
+  "locally placed" and "remotely placed" items.
+- Whether an AP client implements location checking for locally placed items by skipping the usual AP server roundtrip
+  (i.e. sending [LocationChecks](<network%20protocol.md#locationchecks>)
+  then receiving [ReceivedItems](<network%20protocol.md#receiveditems>)
+  ) and directly giving the item to the player, or by doing the AP server roundtrip regardless. I'll call these
+  "locally implemented" items and "remotely implemented" items.
+  - Locally implementing items requires the AP client to know what the locally placed items were without asking an AP
+    server (or else you'd effectively be doing remote items with extra steps). Typically, it gets that information from
+    a patch file, which is one reason why games that already need a patch file are more likely to choose local items.
+  - If items are remotely implemented, the AP client can use [location scouts](<network%20protocol.md#LocationScouts>)
+    to learn what items are placed on what locations. Features that require this information are sometimes mistakenly
+    assumed to require locally implemented items, but location scouts work just as well as patch file data.
+- [The `items_handling` bitflags in the Connect packet](<network%20protocol.md#items_handling-flags>).
+  AP clients with remotely implemented items will typically set all three flags, including "from your own world".
+  Clients with locally implemented items might set only the "from other worlds" flag.
+  - Whether a local items client sets the "starting inventory" flag likely depends on other details. For example, if a ROM
+    is being patched, and starting inventory can be added to that patch, then it makes sense to leave the flag unset.
+
+When people talk about "local vs remote items" as a choice that world devs have to make, they mean deciding whether
+your client will locally or remotely implement the items which happen to be locally placed (or make both
+implementations, or let the player choose an implementation).
+
+Theoretically, the biggest benefit of "local items" is that it allows a solo (single slot) multiworld to be played
+entirely offline, with no AP server, from start to finish. This is similar to a "standalone"/non-AP randomizer,
+except that you still get AP's player options, generation, etc. for free.
+For some games, there are also technical constraints that make certain items easier to implement locally,
+or less glitchy when implemented locally, as long as you're okay with never allowing these items to be placed remotely
+(or offering the player even more options).
+
+The main downside (besides more implementation work) is that "local items" can't support "same slot co-op".
+That's when two players on two different machines connect to the same slot and play together.
+This only works if both players receive all the items for that slot, including ones found by the other player,
+which requires those items to be implemented remotely so the AP server can send them to all of that slot's clients.
+
+So to recap:
+
+- (All) remote items is often the simplest choice, since you have to implement remote items anyway.
+- Remote items enable same slot co-op.
+- Local items enable solo offline play.
+- If you want to support both solo offline play and same slot co-op,
+  you might need to expose local vs remote items as an option to the player.

+# Rule Builder
+
+This document describes the API provided for the rule builder. Using this API provides you with with a simple interface to define rules and the following advantages:
+
+- Rule classes that avoid all the common pitfalls
+- Logic optimization
+- Automatic result caching (opt-in)
+- Serialization/deserialization
+- Human-readable logic explanations for players
+
+## Overview
+
+The rule builder consists of 3 main parts:
+
+1. The rules, which are classes that inherit from `rule_builder.rules.Rule`. These are what you write for your logic. They can be combined and take into account your world's options. There are a number of default rules listed below, and you can create as many custom rules for your world as needed. When assigning the rules to a location or entrance they must be resolved.
+1. Resolved rules, which are classes that inherit from `rule_builder.rules.Rule.Resolved`. These are the optimized rules specific to one player that are set as a location or entrance's access rule. You generally shouldn't be directly creating these but they'll be created when assigning rules to locations or entrances. These are what power the human-readable logic explanations.
+1. The optional rule builder world subclass `CachedRuleBuilderWorld`, which is a class your world can inherit from instead of `World`. It adds a caching system to the rules that will lazy evaluate and cache the result.
+
+## Usage
+
+For the most part the only difference in usage is instead of writing lambdas for your logic, you write static Rule objects. You then must use `world.set_rule` to assign the rule to a location or entrance.
+
+```python
+# In your world's create_regions method
+location = MyWorldLocation(...)
+self.set_rule(location, Has("A Big Gun"))
+```
+
+The rule builder comes with a number of rules by default:
+
+- `True_`: Always returns true
+- `False_`: Always returns false
+- `And`: Checks that all child rules are true (also provided by `&` operator)
+- `Or`: Checks that at least one child rule is true (also provided by `|` operator)
+- `Has`: Checks that the player has the given item with the given count (default 1)
+- `HasAll`: Checks that the player has all given items
+- `HasAny`: Checks that the player has at least one of the given items
+- `HasAllCounts`: Checks that the player has all of the counts for the given items
+- `HasAnyCount`: Checks that the player has any of the counts for the given items
+- `HasFromList`: Checks that the player has some number of given items
+- `HasFromListUnique`: Checks that the player has some number of given items, ignoring duplicates of the same item
+- `HasGroup`: Checks that the player has some number of items from a given item group
+- `HasGroupUnique`: Checks that the player has some number of items from a given item group, ignoring duplicates of the same item
+- `CanReachLocation`: Checks that the player can logically reach the given location
+- `CanReachRegion`: Checks that the player can logically reach the given region
+- `CanReachEntrance`: Checks that the player can logically reach the given entrance
+
+You can combine these rules together to describe the logic required for something. For example, to check if a player either has `Movement ability` or they have both `Key 1` and `Key 2`, you can do:
+
+```python
+rule = Has("Movement ability") | HasAll("Key 1", "Key 2")
+```
+
+> ⚠️ Composing rules with the `and` and `or` keywords will not work. You must use the bitwise `&` and `|` operators. In order to catch mistakes, the rule builder will not let you do boolean operations. As a consequence, in order to check if a rule is defined you must use `if rule is not None`.
+
+### Assigning rules
+
+When assigning the rule you must use the `set_rule` helper to correctly resolve and register the rule.
+
+```python
+self.set_rule(location_or_entrance, rule)
+```
+
+There is also a `create_entrance` helper that will resolve the rule, check if it's `False`, and if not create the entrance and set the rule. This allows you to skip creating entrances that will never be valid. You can also specify `force_creation=True` if you would like to create the entrance even if the rule is `False`.
+
+```python
+self.create_entrance(from_region, to_region, rule)
+```
+
+> ⚠️ If you use a `CanReachLocation` rule on an entrance, you will either have to create the locations first, or specify the location's parent region name with the `parent_region_name` argument of `CanReachLocation`.
+
+You can also set a rule for your world's completion condition:
+
+```python
+self.set_completion_rule(rule)
+```
+
+### Restricting options
+
+Every rule allows you to specify which options it's applicable for. You can provide the argument `options` which is an iterable of `OptionFilter` instances. Rules that pass the options check will be resolved as normal, and those that fail will be resolved as `False`.
+
+If you want a comparison that isn't equals, you can specify with the `operator` argument. The following operators are allowed:
+
+- `eq`: `==`
+- `ne`: `!=`
+- `gt`: `>`
+- `lt`: `<`
+- `ge`: `>=`
+- `le`: `<=`
+- `contains`: `in`
+
+By default rules that are excluded by their options will default to `False`. If you want to default to `True` instead, you can specify `filtered_resolution=True` on your rule.
+
+To check if the player can reach a switch, or if they've received the switch item if switches are randomized:
+
+```python
+rule = (
+    Has("Red switch", options=[OptionFilter(SwitchRando, 1)])
+    | CanReachLocation("Red switch", options=[OptionFilter(SwitchRando, 0)])
+)
+```
+
+To add an extra logic requirement on the easiest difficulty which is ignored for other difficulties:
+
+```python
+rule = (
+    # ...the rest of the logic
+    & Has("QoL item", options=[OptionFilter(Difficulty, Difficulty.option_easy)], filtered_resolution=True)
+)
+```
+
+If you would like to provide option filters when reusing or composing rules, you can use the `Filtered` helper rule:
+
+```python
+common_rule = Has("A") | HasAny("B", "C")
+...
+rule = (
+    Filtered(common_rule, options=[OptionFilter(Opt, 0)]),
+    | Filtered(Has("X") | CanReachRegion("Y"), options=[OptionFilter(Opt, 1)]),
+)
+```
+
+You can also use the & and | operators to apply options to rules:
+
+```python
+common_rule = Has("A")
+easy_filter = [OptionFilter(Difficulty, Difficulty.option_easy)]
+common_rule_only_on_easy = common_rule & easy_filter
+common_rule_skipped_on_easy = common_rule | easy_filter
+```
+
+## Enabling caching
+
+The rule builder provides a `CachedRuleBuilderWorld` base class for your `World` class that enables caching on your rules.
+
+```python
+class MyWorld(CachedRuleBuilderWorld):
+    game = "My Game"
+```
+
+If your world's logic is very simple and you don't have many nested rules, the caching system may have more overhead cost than time it saves. You'll have to benchmark your own world to see if it should be enabled or not.
+
+### Item name mapping
+
+If you have multiple real items that map to a single logic item, add a `item_mapping` class dict to your world that maps actual item names to real item names so the cache system knows what to invalidate.
+
+For example, if you have multiple `Currency x<num>` items on locations, but your rules only check a singular logical `Currency` item, eg `Has("Currency", 1000)`, you'll want to map each numerical currency item to the single logical `Currency`.
+
+```python
+class MyWorld(CachedRuleBuilderWorld):
+    item_mapping = {
+        "Currency x10": "Currency",
+        "Currency x50": "Currency",
+        "Currency x100": "Currency",
+        "Currency x500": "Currency",
+    }
+```
+
+## Defining custom rules
+
+You can create a custom rule by creating a class that inherits from `Rule` or any of the default rules. You must provide the game name as an argument to the class. It's recommended to use the `@dataclass` decorator to reduce boilerplate, and to also provide your world as a type argument to add correct type checking to the `_instantiate` method.
+
+You must provide or inherit a `Resolved` child class that defines an `_evaluate` method. This class will automatically be converted into a frozen `dataclass`. If your world has caching enabled you may need to define one or more dependencies functions as outlined below.
+
+To add a rule that checks if the user has enough mcguffins to goal, with a randomized requirement:
+
+```python
+@dataclasses.dataclass()
+class CanGoal(Rule["MyWorld"], game="My Game"):
+    @override
+    def _instantiate(self, world: "MyWorld") -> Rule.Resolved:
+        # caching_enabled only needs to be passed in when your world inherits from CachedRuleBuilderWorld
+        return self.Resolved(world.required_mcguffins, player=world.player, caching_enabled=True)
+
+    class Resolved(Rule.Resolved):
+        goal: int
+
+        @override
+        def _evaluate(self, state: CollectionState) -> bool:
+            return state.has("McGuffin", self.player, count=self.goal)
+
+        @override
+        def item_dependencies(self) -> dict[str, set[int]]:
+            # this function is only required if you have caching enabled
+            return {"McGuffin": {id(self)}}
+
+        @override
+        def explain_json(self, state: CollectionState | None = None) -> list[JSONMessagePart]:
+            # this method can be overridden to display custom explanations
+            return [
+                {"type": "text", "text": "Goal with "},
+                {"type": "color", "color": "green" if state and self(state) else "salmon", "text": str(self.goal)},
+                {"type": "text", "text": " McGuffins"},
+            ]
+```
+
+Your custom rule can also resolve to builtin rules instead of needing to define your own:
+
+```python
+@dataclasses.dataclass()
+class ComplicatedFilter(Rule["MyWorld"], game="My Game"):
+    def _instantiate(self, world: "MyWorld") -> Rule.Resolved:
+        if world.some_precalculated_bool:
+            return Has("Item 1").resolve(world)
+        if world.options.some_option:
+            return CanReachRegion("Region 1").resolve(world)
+        return False_().resolve(world)
+```
+
+### Item dependencies
+
+If your world inherits from `CachedRuleBuilderWorld` and there are items that when collected will affect the result of your rule evaluation, it must define an `item_dependencies` function that returns a mapping of the item name to the id of your rule. These dependencies will be combined to inform the caching system. It may be worthwhile to define this function even when caching is disabled as more things may use it in the future.
+
+```python
+@dataclasses.dataclass()
+class MyRule(Rule["MyWorld"], game="My Game"):
+    class Resolved(Rule.Resolved):
+        item_name: str
+
+        @override
+        def item_dependencies(self) -> dict[str, set[int]]:
+            return {self.item_name: {id(self)}}
+```
+
+All of the default `Has*` rules define this function already.
+
+### Region dependencies
+
+If your custom rule references other regions, it must define a `region_dependencies` function that returns a mapping of region names to the id of your rule regardless of if your world inherits from `CachedRuleBuilderWorld`. These dependencies will be combined to register indirect connections when you set this rule on an entrance and inform the caching system if applicable.
+
+```python
+@dataclasses.dataclass()
+class MyRule(Rule["MyWorld"], game="My Game"):
+    class Resolved(Rule.Resolved):
+        region_name: str
+
+        @override
+        def region_dependencies(self) -> dict[str, set[int]]:
+            return {self.region_name: {id(self)}}
+```
+
+The default `CanReachLocation`, `CanReachRegion`, and `CanReachEntrance` rules define this function already.
+
+### Location dependencies
+
+If your custom rule references other locations, it must define a `location_dependencies` function that returns a mapping of the location name to the id of your rule regardless of if your world inherits from `CachedRuleBuilderWorld`. These dependencies will be combined to register indirect connections when you set this rule on an entrance and inform the caching system if applicable.
+
+```python
+@dataclasses.dataclass()
+class MyRule(Rule["MyWorld"], game="My Game"):
+    class Resolved(Rule.Resolved):
+        location_name: str
+
+        @override
+        def location_dependencies(self) -> dict[str, set[int]]:
+            return {self.location_name: {id(self)}}
+```
+
+The default `CanReachLocation` rule defines this function already.
+
+### Entrance dependencies
+
+If your custom rule references other entrances, it must define a `entrance_dependencies` function that returns a mapping of the entrance name to the id of your rule regardless of if your world inherits from `CachedRuleBuilderWorld`. These dependencies will be combined to register indirect connections when you set this rule on an entrance and inform the caching system if applicable.
+
+```python
+@dataclasses.dataclass()
+class MyRule(Rule["MyWorld"], game="My Game"):
+    class Resolved(Rule.Resolved):
+        entrance_name: str
+
+        @override
+        def entrance_dependencies(self) -> dict[str, set[int]]:
+            return {self.entrance_name: {id(self)}}
+```
+
+The default `CanReachEntrance` rule defines this function already.
+
+### Rule explanations
+
+Resolved rules have a default implementation for `explain_json` and `explain_str` functions. The former optionally accepts a `CollectionState` and returns a list of `JSONMessagePart` appropriate for `print_json` in a client. It will display a human-readable message that explains what the rule requires. The latter is similar but returns a string. It is useful when debugging. There is also a `__str__` method defined to check what a rule is without a state.
+
+To implement a custom message with a custom rule, override the `explain_json` and/or `explain_str` method on your `Resolved` class:
+
+```python
+class MyRule(Rule, game="My Game"):
+    class Resolved(Rule.Resolved):
+        @override
+        def explain_json(self, state: CollectionState | None = None) -> list[JSONMessagePart]:
+            has_item = state and state.has("growth spurt", self.player)
+            color = "yellow"
+            start = "You must be "
+            if has_item:
+                start = "You are "
+                color = "green"
+            elif state is not None:
+                start = "You are not "
+                color = "salmon"
+            return [
+                {"type": "text", "text": start},
+                {"type": "color", "color": color, "text": "THIS"},
+                {"type": "text", "text": " tall to beat the game"},
+            ]
+
+        @override
+        def explain_str(self, state: CollectionState | None = None) -> str:
+            if state is None:
+                return str(self)
+            if state.has("growth spurt", self.player):
+                return "You ARE this tall and can beat the game"
+            return "You are not THIS tall and cannot beat the game"
+
+        @override
+        def __str__(self) -> str:
+            return "You must be THIS tall to beat the game"
+```
+
+### Cache control
+
+By default your custom rule will work through the cache system as any other rule if caching is enabled. There are two class attributes on the `Resolved` class you can override to change this behavior.
+
+- `force_recalculate`: Setting this to `True` will cause your custom rule to skip going through the caching system and always recalculate when being evaluated. When a rule with this flag enabled is composed with `And` or `Or` it will cause any parent rules to always force recalculate as well. Use this flag when it's difficult to determine when your rule should be marked as stale.
+- `skip_cache`: Setting this to `True` will also cause your custom rule to skip going through the caching system when being evaluated. However, it will **not** affect any other rules when composed with `And` or `Or`, so it must still define its `*_dependencies` functions as required. Use this flag when the evaluation of this rule is trivial and the overhead of the caching system will slow it down.
+
+### Caveats
+
+- Ensure you are passing `caching_enabled=True` in your `_instantiate` function when creating resolved rule instances if your world has opted into caching.
+- Resolved rules are forced to be frozen dataclasses. They and all their attributes must be immutable and hashable.
+- If your rule creates child rules ensure they are being resolved through the world rather than creating `Resolved` instances directly.
+
+## Serialization
+
+The rule builder is intended to be written first in Python for optimization and type safety. To facilitate exporting the rules to a client or tracker, rules have a `to_dict` method that returns a JSON-compatible dict. Since the location and entrance logic structure varies greatly from world to world, the actual JSON dumping is left up to the world dev.
+
+The dict contains a `rule` key with the name of the rule, an `options` key with the rule's list of option filters, and an `args` key that contains any other arguments the individual rule has. For example, this is what a simple `Has` rule would look like:
+
+```python
+{
+    "rule": "Has",
+    "options": [],
+    "args": {
+        "item_name": "Some item",
+        "count": 1,
+    },
+}
+```
+
+For `And` and `Or` rules, instead of an `args` key, they have a `children` key containing a list of their child rules in the same serializable format:
+
+```python
+{
+    "rule": "And",
+    "options": [],
+    "children": [
+        ...,  # each serialized rule
+    ]
+}
+```
+
+A full example is as follows:
+
+```python
+rule = And(
+    Has("a", options=[OptionFilter(ToggleOption, 0)]),
+    Or(Has("b", count=2), CanReachRegion("c"), options=[OptionFilter(ToggleOption, 1)]),
+)
+assert rule.to_dict() == {
+    "rule": "And",
+    "options": [],
+    "children": [
+        {
+            "rule": "Has",
+            "options": [
+                {
+                    "option": "worlds.my_world.options.ToggleOption",
+                    "value": 0,
+                    "operator": "eq",
+                },
+            ],
+            "args": {
+                "item_name": "a",
+                "count": 1,
+            },
+        },
+        {
+            "rule": "Or",
+            "options": [
+                {
+                    "option": "worlds.my_world.options.ToggleOption",
+                    "value": 1,
+                    "operator": "eq",
+                },
+            ],
+            "children": [
+                {
+                    "rule": "Has",
+                    "options": [],
+                    "args": {
+                        "item_name": "b",
+                        "count": 2,
+                    },
+                },
+                {
+                    "rule": "CanReachRegion",
+                    "options": [],
+                    "args": {
+                        "region_name": "c",
+                    },
+                },
+            ],
+        },
+    ],
+}
+```
+
+### Custom serialization
+
+To define a different format for your custom rules, override the `to_dict` function:
+
+```python
+class BasicLogicRule(Rule, game="My Game"):
+    items = ("one", "two")
+
+    def to_dict(self) -> dict[str, Any]:
+        # Return whatever format works best for you
+        return {
+            "logic": "basic",
+            "items": self.items,
+        }
+```
+
+If your logic has been done in custom JSON first, you can define a `from_dict` class method on your rules to parse it correctly:
+
+```python
+class BasicLogicRule(Rule, game="My Game"):
+    @classmethod
+    def from_dict(cls, data: Mapping[str, Any], world_cls: type[World]) -> Self:
+        items = data.get("items", ())
+        return cls(*items)
+```
