-This mod adds rsync to openssh-server, to be installed/updated during container start.
+This mod adds docker and docker-compose to code-server, to be installed/updated during container start.
 
-In openssh-server docker arguments, set an environment variable `DOCKER_MODS=linuxserver/mods:openssh-server-rsync`
+**IMPORTANT NOTE**: For docker access inside code-server, a volume mapping needs to be added for `/var/run/docker.sock:/var/run/docker.sock` in code-server docker run/create/compose.
 
-# Mod creation instructions
+In code-server docker arguments, set an environment variable `DOCKER_MODS=linuxserver/mods:code-server-docker` to enable.
 
-* Ask the team to create a new branch named `<baseimagename>-<modname>`. Baseimage should be the name of the image the mod will be applied to. The new branch will be based on the `template` branch.
-* Fork the repo, checkout the template branch.
-* Edit the `Dockerfile` for the mod. `Dockerfile.complex` is only an example and included for reference; it should be deleted when done.
-* Inspect the `root` folder contents. Edit, add and remove as necessary.
-* Edit this readme with pertinent info, delete thse instructions.
-* Finally edit the `travis.yml`. Customize the build branch,and the vars for `BASEIMAGE` and `MODNAME`
-* Submit PR against the branch created by the team
+If adding multiple mods, enter them in an array separated by `|`, such as `DOCKER_MODS=linuxserver/mods:code-server-docker|linuxserver/mods:code-server-mod2`
