It is important to note to end users of this system that there are not only extreme security implications to consuming files from souces outside of our control, but by leveraging community Mods you essentially lose direct support from the core LinuxServer team. Our first and foremost troubleshooting step will be to remove the `DOCKER_MODS` environment variable when running into issues and replace the container with a clean LSIO one.

In this repository we will be going over two basic methods of making a Mod along with an example of the GitHub Actions build logic to get this into a Dockerhub and/or GitHub Container Registry endpoint. Though we are not officially endorsing GitHub Actions here it is built in to GitHub repositories and forks making it very easy to get started. If you prefer others feel free to use them as long as build jobs are transparent.
