-# docker-mc-fabric
-This repository helps you easily setup a modded Minecraft server using the
-[Fabric mod loader](https://fabricmc.net/).
+# Build arguments
+Only one build argument is required, namely `FABRIC_VERSION`. This is the
+version of Fabric you wish to install. You can find the list of versions
+[here](https://fabricmc.net/use/). For example, you can then set
+`FABRIC_VERSION=0.6.1.51` in the `.env` file.
 
-## Installing docker
-You can follow the instructions
-[here](https://docs.docker.com/engine/install/).
+# Environment variables
+The two possible environment variables are `XMS` and `XMX`. These specify the
+initial RAM & maximum RAM usage, respectively. Only `XMS` is required; `XMX` is
+just set to the same value as `XMS` if not specified. You must specify them as
+a number, e.g. `XMS=4`. This number represents a quantity of gigabytes.
 
-## Building the image
-To build the image, you must specify the Fabric version using the `VERSION`
-build argument. You can either do this using `docker`:
+# Mount points
+There a three useful mount points defined:
 
-`docker build -t mc-fabric-server:latest --build-arg VERSION=0.6.1.51 .`
-
-or using `docker-compose`, by specifying the argument in the
-`docker-compose.yml` file and running:
-
-`docker-compose build`
-
-See the provided `docker-compose.yml` file for an example of how to specify the
-build argument.
-
-## Useful mount points
-The container has three useful mount points:
 * `/mc/config`: this is where all server config files reside.
 * `/mc/config/mods`: this is where all mods should be placed.
 * `/mc/worlds`: this is where the world files are stored.
 
-I recommend mounting these to either a local directory or a volume, as to not
-lose the server data.
+You can mount these directories somewhere in the host file system by specifying
+the mount paths in the `.env` file. These can be both absolute or relative
+paths.
 
-## Environment variables
-The container has two environment variables which can be set, namely `XMS` and
-`XMX`. If `XMX` is not set, it will use `XMS`'s value by default. Note that
-their value is expected to be an integer, which is then used as a quantity for
-gigabytes. Therefore, only gigabyte precision is possible.
+# Other config variables
+The only other config variable is `PORT`. This specifies on what port your
+server will be discoverable over the internet. The default Minecraft port is
+`25565`.

-## Running the server
-### docker
-You can start the server with the following command:
-
-```
-docker run \
-    --rm \
-    --interactive \
-    --tty \
-    --publish '25565:25565' \
-    --detach \
-    mc-fabric-server:latest
-```
-
-Or, more compact:
-
-`docker run --rm -dit -p '25565:25565' mc-fabric-server:latest`
-
-This will start the server and run it in the background.
-
-### docker-compose
-If you prefer to use `docker-compose` (which I recommend), you can use the
-provided `docker-compose.yml` file and edit it to suit your needs. By default,
-it creates volumes for the three major mount points, and opens up port `25565`.
-Then, you can start the server using `docker-compose up --detach` or
-`docker-compose up -d`, because no one likes typing long commands.
