+# Deploy Using Containers
+
+If you just want to play and there is a compiled version available on the [Archipelago releases page](https://github.com/ArchipelagoMW/Archipelago/releases), use that version.
+To build the full Archipelago software stack, refer to [Running From Source](running%20from%20source.md).
+Follow these steps to build and deploy a containerized instance of the web host software, optionally integrating [Gunicorn](https://gunicorn.org/) WSGI HTTP Server running behind the [nginx](https://nginx.org/) reverse proxy.
+
+
+## Building the Container Image
+
+What you'll need:
+ * A container runtime engine such as:
+   * [Docker](https://www.docker.com/)
+   * [Podman](https://podman.io/)
+     * For running with rootless podman, you need to ensure all ports used are usable rootless, by default ports less than 1024 are root only. See [the official tutorial](https://github.com/containers/podman/blob/main/docs/tutorials/rootless_tutorial.md) for details.
+
+Starting from the root repository directory, the standalone Archipelago image can be built and run with the command:
+`docker build -t archipelago .`
+Or:
+`podman build -t archipelago .`
+
+It is recommended to tag the image using `-t` to more easily identify the image and run it.
+
+
+## Running the Container
+
+Running the container can be performed using:
+`docker run --network host archipelago`
+Or:
+`podman run --network host archipelago`
+
+The Archipelago web host requires access to multiple ports in order to host game servers simultaneously. To simplify configuration for this purpose, specify `--network host`.
+
+Given the default configuration, the website will be accessible at the hostname/IP address (localhost if run locally) of the machine being deployed to, at port 80. It can be configured by creating a YAML file and mapping a volume to the container when running initially:
+`docker run archipelago --network host -v /path/to/config.yaml:/app/config.yaml`
+See `docs/webhost configuration sample.yaml` for example.
+
+
+## Using Docker Compose
+
+An example [docker compose](../deploy/docker-compose.yml) file can be found in [deploy](../deploy), along with example configuration files used by the services it orchestrates. Using these files as-is will spin up two separate archipelago containers with special modifications to their runtime arguments, in addition to deploying an `nginx` reverse proxy container.
+
+To deploy in this manner, from the ["deploy"](../deploy) directory, run:
+`docker compose up -d`
+
+### Services
+
+The `docker-compose.yaml` file defines three services:
+  * multiworld:
+    * Executes the main `WebHost` process, using the [example config](../deploy/example_config.yaml), and overriding with a secondary [selflaunch example config](../deploy/example_selflaunch.yaml). This is because we do not want to launch the website through this service.
+  * web:
+    * Executes `gunicorn` using its [example config](../deploy/example_gunicorn.conf.py), which will bind it to the `WebHost` application, in effect launching it.
+    * We mount the main [config](../deploy/example_config.yaml) without an override to specify that we are launching the website through this service.
+    * No ports are exposed through to the host.
+  * nginx:
+    * Serves as a reverse proxy with `web` as its upstream.
+    * Directs all HTTP traffic from port 80 to the upstream service.
+    * Exposed to the host on port 8080. This is where we can reach the website.
+
+### Configuration
+
+As these are examples, they can be copied and modified. For instance setting the value of `HOST_ADDRESS` in [example config](../deploy/example_config.yaml) to host machines local IP address, will expose the service to its local area network.
+
+The configuration files may be modified to handle for machine-specific optimizations, such as:
+  * Web pages responding too slowly
+    * Edit [the gunicorn config](../deploy/example_gunicorn.conf.py) to increase thread and/or worker count.
+  * Game generation stalls
+    * Increase the generator count in [selflaunch config](../deploy/example_selflaunch.yaml)
+  * Gameplay lags
+    * Increase the hoster count in [selflaunch config](../deploy/example_selflaunch.yaml)
+
+Changes made to `docker-compose.yaml` can be applied by running `docker compose up -d`, while those made to other files are applied by running `docker compose restart`.
+
+
+## Windows
+
+It is possible to carry out these deployment steps on Windows under [Windows Subsystem for Linux](https://learn.microsoft.com/en-us/windows/wsl/install).
+
+
+## Optional: A Link to the Past Enemizer
+
+Only required to generate seeds that include A Link to the Past with certain options enabled. You will receive an
+error if it is required.
+Enemizer can be enabled on `x86_64` platform architecture, and is included in the image build process. Enemizer requires a version 1.0 Japanese "Zelda no Densetsu" `.sfc` rom file to be placed in the application directory:
+`docker run archipelago -v "/path/to/zelda.sfc:/app/Zelda no Densetsu - Kamigami no Triforce (Japan).sfc"`.
+Enemizer is not currently available for `aarch64`.
+
+
+## Optional: Git
+
+Building the image requires a local copy of the ArchipelagoMW source code.
+Refer to [Running From Source](running%20from%20source.md#optional-git).
