-Archipelago was directly forked from bonta0's `multiworld_31` branch of ALttPEntranceRandomizer (this project has a long legacy of its own, please check it out linked above) on January 12, 2020. The repository was then named to _MultiWorld-Utilities_ to better encompass its intended function. As Archipelago matured, then known as "Berserker's MultiWorld" by some, we found it necessary to transform our repository into a root level repository (as opposed to a 'forked repo') and change the name (which came later) to better reflect our project.

+# Frequently Asked Questions
+
+## What is a randomizer?
+
+A randomizer is a modification of a game which reorganizes the items required to progress through that game. A
+normal play-through might require you to use item A to unlock item B, then C, and so forth. In a randomized
+game, you might first find item C, then A, then B.
+
+This transforms the game from a linear experience into a puzzle, presenting players with a new challenge each time they
+play. Putting items in non-standard locations can require the player to think about the game world and the items they
+encounter in new and interesting ways.
+
+## What is a multiworld?
+
+While a randomizer shuffles a game, a multiworld randomizer shuffles that game for multiple players. For example, in a
+two player multiworld, players A and B each get their own randomized version of a game, called a world. In each
+player's game, they may find items which belong to the other player. If player A finds an item which belongs to
+player B, the item will be sent to player B's world over the internet. This creates a cooperative experience, requiring
+players to rely upon each other to complete their game.
+
+## What does multi-game mean?
+
+While a multiworld game traditionally requires all players to be playing the same game, a multi-game multiworld allows
+players to randomize any of the supported games, and send items between them. This allows players of different
+games to interact with one another in a single multiplayer environment.  Archipelago supports multi-game multiworld.
+Here is a list of our [Supported Games](https://archipelago.gg/games).
+
+## Can I generate a single-player game with Archipelago?
+
+Yes. All of our supported games can be generated as single-player experiences both on the website and by installing 
+the Archipelago generator software. The fastest way to do this is on the website. Find the Supported Game you wish to
+play, open the Settings Page, pick your settings, and click Generate Game.
+
+## How do I get started?
+
+We have a [Getting Started](https://archipelago.gg/tutorial/Archipelago/setup/en) guide that will help you get the
+software set up. You can use that guide to learn how to generate multiworlds. There are also basic instructions for
+including multiple games, and hosting multiworlds on the website for ease and convenience.
+
+If you are ready to start randomizing games, or want to start playing your favorite randomizer with others, please join
+our discord server at the [Archipelago Discord](https://discord.gg/8Z65BR2). There are always people ready to answer
+any questions you might have.
+
+## What are some common terms I should know?
+
+As randomizers and multiworld randomizers have been around for a while now, there are quite a few common terms used
+by the communities surrounding them. A list of Archipelago jargon and terms commonly used by the community can be
+found in the [Glossary](/glossary/en).
+
+## Does everyone need to be connected at the same time?
+
+There are two different play-styles that are common for Archipelago multiworld sessions. These sessions can either
+be considered synchronous (or "sync"), where everyone connects and plays at the same time, or asynchronous (or "async"),
+where players connect and play at their own pace. The setup for both is identical. The difference in play-style is how
+you and your friends choose to organize and play your multiworld. Most groups decide on the format before creating
+their multiworld.
+
+If a player must leave early, they can use Archipelago's release system. When a player releases their game, all items
+in that game belonging to other players are sent out automatically. This allows other players to continue to play
+uninterrupted. Here is a list of all of our [Server Commands](https://archipelago.gg/tutorial/Archipelago/commands/en).
+
+## What happens if an item is placed somewhere it is impossible to get?
+
+The randomizer has many strict sets of rules it must follow when generating a game. One of the functions of these rules
+is to ensure items necessary to complete the game will be accessible to the player. Many games also have a subset of
+rules allowing certain items to be placed in normally unreachable locations, provided the player has indicated they are
+comfortable exploiting certain glitches in the game.
+
+## I want to add a game to the Archipelago randomizer. How do I do that?
+
+The best way to get started is to take a look at our code on GitHub:  
+[Archipelago GitHub Page](https://github.com/ArchipelagoMW/Archipelago).
+
+There, you will find examples of games in the `worlds` folder:  
+[/worlds Folder in Archipelago Code](https://github.com/ArchipelagoMW/Archipelago/tree/main/worlds).
+
+You may also find developer documentation in the `docs` folder:  
+[/docs Folder in Archipelago Code](https://github.com/ArchipelagoMW/Archipelago/tree/main/docs).
+
+If you have more questions, feel free to ask in the **#ap-world-dev** channel on our Discord.

-game, you might first find item C, then A, then B.
-
-This transforms games from a linear experience into a puzzle, presenting players with a new challenge each time they
-play a randomized game. Putting items in non-standard locations can require the player to think about the game world and
-the items they encounter in new and interesting ways.
-
-## What happens if an item is placed somewhere it is impossible to get?
-
-The randomizer has many strict sets of rules it must follow when generating a game. One of the functions of these rules
-is to ensure items necessary to complete the game will be accessible to the player. Many games also have a subset of
-rules allowing certain items to be placed in normally unreachable locations, provided the player has indicated they are
-comfortable exploiting certain glitches in the game.
-
-## What is a multi-world?
-
-While a randomizer shuffles a game, a multi-world randomizer shuffles that game for multiple players. For example, in a
-two player multi-world, players A and B each get their own randomized version of a game, called a world. In each player's
-game, they may find items which belong to the other player. If player A finds an item which belongs to player B, the
-item will be sent to player B's world over the internet.
-
-This creates a cooperative experience during multi-world games, requiring players to rely upon each other to complete
-their game.
-
-## What happens if a person has to leave early?
-
-If a player must leave early, they can use Archipelago's release system. When a player releases their game, all the
-items in that game which belong to other players are sent out automatically, so other players can continue to play.
-
-## What does multi-game mean?
-
-While a multi-world game traditionally requires all players to be playing the same game, a multi-game multi-world allows
-players to randomize any of a number of supported games, and send items between them. This allows players of different
-games to interact with one another in a single multiplayer environment.
-
-## Can I generate a single-player game with Archipelago?
-
-Yes. All our supported games can be generated as single-player experiences, and so long as you download the software,
-the website is not required to generate them.
-
-## How do I get started?
-
-If you are ready to start randomizing games, or want to start playing your favorite randomizer with others, please join
-our discord server at the [Archipelago Discord](https://discord.gg/8Z65BR2). There are always people ready to answer
-any questions you might have.
-
-## What are some common terms I should know?
-
-As randomizers and multiworld randomizers have been around for a while now there are quite a lot of common terms
-and jargon that is used in conjunction by the communities surrounding them. For a lot of the terms that are more common
-to Archipelago and its specific systems please see the [Glossary](/glossary/en).
-
-## I want to add a game to the Archipelago randomizer. How do I do that?
-
-The best way to get started is to take a look at our code on GitHub
-at [Archipelago GitHub Page](https://github.com/ArchipelagoMW/Archipelago).
-
-There you will find examples of games in the worlds folder
-at [/worlds Folder in Archipelago Code](https://github.com/ArchipelagoMW/Archipelago/tree/main/worlds).
-
-You may also find developer documentation in the docs folder
-at [/docs Folder in Archipelago Code](https://github.com/ArchipelagoMW/Archipelago/tree/main/docs).
-
-If you have more questions, feel free to ask in the **#archipelago-dev** channel on our Discord.
