-# Mod creation instructions
-
-* 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 newly created 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 these 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-powershell|linuxserver/mods:code-server-mod2`
