1. The script [`setup.sh`][github-file-setupsh] is supplied with this project. It supports you in **configuring and administrating** your server. Information on how to get it and how to use it is available [on a dedicated page][docs-setupsh].
2. Be aware that advanced tasks may still require tweaking environment variables, reading through documentation and sometimes inspecting your running container for debugging purposes. After all, a mail server is a complex arrangement of various programs.
3. A list of all configuration options is documented on [the ENV page][docs-environment]. The [`README.md`][github-file-readme] is a good starting point to understand what this image is capable of.
If you'd like to change, patch or alter files or behavior of `docker-mailserver`, you can use a script. Just place it in the `config/` folder that is created on startup and call it `user-patches.sh`. If you'd like to see the full documentation and an example, visit the ['Modifications via Script' page][docs-userpatches].
