+$GITHUB_REPONAME
+
+$DESCRIPTION
+
+[![$CREATOR_REPONAME]($EXAMPLE_IMAGE_LINK)](https://github.com/$CREATOR_NAME/$CREATOR_REPO)
+
+---
+
+Creates a Container which runs [CREATOR_USERNAME's](https://github.com/$CREATOR_USERNAME) [$CREATOR_REPONAME](https://github.com/$CREATOR_USERNAME/$CREATOR_REPONAME), with [lsiobase/alpine](https://hub.docker.com/r/lsiobase/alpine) as the base image, as seen on $EXAMPLE_SITE_LINK.
+
+The lasiobase/alpine image is a custom base image built with [Alpine linux](https://alpinelinux.org/) and [S6 overlay](https://github.com/just-containers/s6-overlay).
+Using this image allows us to use the same user/group ids in the container as on the host, making file transfers much easier
+
+## Deployment
+
+### Pre-built images
+
+```docker-compose.yml
+version: '3.6'
+services:
+  $GITHUB_REPONAME:
+    container_name: $GITHUB_REPONAME
+    image: griefed/$GITHUB_REPONAME
+    restart: unless-stopped
+    volumes:
+      - ./path/to/config:/config
+      - ./path/to/data:/data
+    environment:
+      - TZ=Europe/Berlin
+      - PUID=1000  # User ID
+      - PGID=1000  # Group ID
+    ports:
+      - 8080:$COTNAINER_PORT
+```
+
+## Configuration
+
+Configuration | Explanation
+------------ | -------------
+[Restart policy](https://docs.docker.com/compose/compose-file/#restart) | "no", always, on-failure, unless-stopped
+config volume | Contains config files and logs.
+data volume | Contains your/the containers important data.
+TZ | Timezone
+PUID | for UserID
+PGID | for GroupID
+ports | The port where the service will be available at.
+
+## User / Group Identifiers
+
+When using volumes, permissions issues can arise between the host OS and the container. [Linuxserver.io](https://www.linuxserver.io/) avoids this issue by allowing you to specify the user `PUID` and group `PGID`.
+
+Ensure any volume directories on the host are owned by the same user you specify and any permissions issues will vanish like magic.
+
+In this instance `PUID=1000` and `PGID=1000`, to find yours use `id user` as below:
+
+```
+  $ id username
+    uid=1000(dockeruser) gid=1000(dockergroup) groups=1000(dockergroup)
+```
+
+### Raspberry Pi & building the image yourself
+
+Using the [Dockerfile](https://github.com/Griefed/$GITHUB_REPONAME/Dockerfile), this container can be built and run on a Raspberry Pi.
+I've tested it on a Raspberry Pi 3B.
+
+#### docker-compose.yml
+
+```docker-compose.yml
+version: '3.6'
+services:
+  $GITHUB_REPONAME:
+    container_name: $GITHUB_REPONAME
+    build: ./$GITHUB_REPONAME/
+    restart: unless-stopped
+    volumes:
+      - ./path/to/config/files:/config
+      - ./path/to/data:/data
+    environment:
+      - TZ=Europe/Berlin
+      - PUID=1000  # User ID
+      - PGID=1000  # Group ID
+    ports:
+      - 8080:$CONTAINER_PORT
+```
+
+1. Clone the repository: `git clone https://github.com/Griefed/$GITHUB_REPONAME.git ./$GITHUB_REPONAME`
+1. Prepare docker-compose.yml file as seen above
+1. `docker-compose up -d --build $GITHUB_REPONAME`
+1. Visit IP.ADDRESS.OF.HOST:8080
+1. ???
+1. Profit!
