 # Docker
 
-## Standalone
+The Darkflame Server is automatically built and published as a Docker Container / [OCI](https://opencontainers.org/) Image to the GitHub Container Registry at:
+[`ghcr.io/darkflameuniverse/darkflameserver`](https://github.com/DarkflameUniverse/DarkflameServer/pkgs/container/darkflameserver).
+
+## Compose
+
+You can use the `docker-compose` tool to [setup a MariaDB database](#database-setup), run the Darkflame Server and manage it with [Nexus Dashboard](https://github.com/DarkflameUniverse/NexusDashboard) all
+at once. For that:
+
+- [Install Docker Desktop](https://docs.docker.com/get-docker/)
+- Open the directory that contains your LU Client
+  - If the `legouniverse.exe` is in a subfolder called `client`, you're good to go. There may also be a folder `versions`.
+  - Otherwise, create a new `client` folder and move the exe and everything else (e.g. `res` and `locale`) in there. This is necessary to work around a bug in the client that will prevent that you to log back in after getting disconnected.
+- Download the [docker-compose.yml](docker-compose.yml) file and place it next to `client`.
+- Download the [.env.example](.env.example) file and place it next to `client` with the file name `.env`
+  - You may get warnings that this name starts with a dot, acknowledge those, this is intentional. Depending on your operating system, you may need to activate showing hidden files (e.g. Ctrl-H in Gnome on Linux) and/or file extensions ("File name extensions" in the "View" tab on Windows).
+  - Update the `ACCOUNT_MANAGER_SECRET` and `MARIADB_PASSWORD` with strong random passwords.
+    - Use a password generator like <https://keygen.io>
+    - Avoid `:` and `@` characters
+    - Once the database user is created, changing the password will not update it, so the server will just fail to connect.
+  - Set `EXTERNAL_IP` to your LAN IP or public IP if you want to host the game for friends & family
+- Open a terminal in the folder with the `docker-compose.yml` and `client`
+- Run `docker compose up -d`
+  - This might require `sudo` on Linux, and a recent version of [docker compose](https://docs.docker.com/compose/install/)
+- Run `docker exec -it dlu-darkflameserver-1 /app/MasterServer -a` and follow the instructions to create the initial admin account
+- Open <http://localhost:8000> to access Nexus Dashboard with the admin account to create normal users
+- Set `AUTHSERVERIP=0:localhost` in `client/boot.cfg`
+  - Replace `localhost` with the value of `EXTERNAL_IP` if you changed that earlier.
+  - Also make sure `UGCUSE3DSERVICES=7:` is set to `0`
+- Launch `legouniverse.exe`
 
-For standalone deployment, you can use the image provided via Github's Container Repository:
-`ghcr.io/darkflameuniverse/darkflameserver`
+## Standalone
 
 This assumes that you have a database deployed to your host or in another docker container.
 
@@ -376,14 +404,6 @@ You will need to replace the `/path/to/`'s to reflect the paths on your host.
 
 Any config option in the `.ini`'s can be overridden with environmental variables: Ex: `log_to_console=1` from `shared_config.ini` would be overidden like  `-e LOG_TO_CONSOLE=0`
 
-## Compose
-
-See the [compose](docker-compose.yml) file in the root of the repo.
-
-This compose file is for a full deployment: MariaDB, DarkflameServer, and Nexus Dashboard.
-
-All of the environmental options are listed in the compose file so the can be pass through, or you can edit the compose file to suit your specific needs

 This is a Work in Progress, but below are some quick links to documentaion for systems and structs in the server
