-In openssh-server docker arguments, set an environment variable `DOCKER_MODS=linuxserver/mods:openssh-server-rsync`

+If adding multiple mods, enter them in an array separated by `|`, such as `DOCKER_MODS=linuxserver/mods:code-server-dotnet|linuxserver/mods:code-server-mod2`
 
-# Mod creation instructions
+All current [lts releases](https://dotnet.microsoft.com/download/dotnet-core) will be made available inside the container (3.1.403 and 2.1.811 as of 2020/10/14).
 
-* Fork the repo, create a new branch based on the branch `template`.
-* 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`.
-* 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.
-* Submit PR against the branch created by the team.
+The binaries are accessible at `/dotnet_<sdkversion>/dotnet` for each respective version.
+
+The latest version binary is symlinked from `/usr/local/bin/dotnet` so it can be called via `dotnet` from anywhere.
