+To get up and running with Lidarr docker you can use the https://github.com/linuxserver/docker-lidarr image (alternatives also exist).
+
+Example:
+
+```bash
+docker create \
+  --name=lidarr \
+  -v <path to data>:/config \
+  -v <path to downloads>:/downloads \
+  -v <path to music>:/music \
+  -e PGID=<gid> -e PUID=<uid>  \
+  -p 8686:8686 \
+  linuxserver/lidarr
+```
+
+## Parameters
+
+The parameters are split into two halves, separated by a colon, the left hand side representing the host and the right the container side. 
+For example with a port -p external:internal - what this shows is the port mapping from internal to external of the container.
+So -p 8080:80 would expose port 80 from inside the container to be accessible from the host's IP on port 8080
+http://192.168.x.x:8080 would show you what's running INSIDE the container on port 80.
+
+
+
+| Parameter | Function |
+| :---: | --- |
+| `-p 8686` | the port(s) |
+| `-v /config` | Contains your config files|
+| `-v /downloads` | Path to your download folder for music |
+| `-v /music` | Path to your music library |
+| `-e PGID` | for GroupID, see below for explanation |
+| `-e PUID` | for UserID, see below for explanation |
+
+
