+- Setting a log file is strongly recommend. This makes it much easier to troubleshoot problems.
+- To use a config file in Docker, mount `/config` to the container and Unpackerr will write a config file.
+  - Update the new file and restart the container.
+- When using a config file you must uncomment at minimum the `[[header]]` <font color="gray">
+  ex. `[[radarr]]`</font>, `url` and `api_key`.
+- Uncomment means remove the hash `#` at the beginning of the line.

-- Setting a log file is strongly recommend. This makes it much easier to troubleshoot problems.
-- To use a config file in Docker, mount `/config` to the container and Unpackerr will write a config file.
-- When using a config file you must uncomment at minimum the `[[header]]` (`[[radarr]]`), `url` and `api_key`.
-- Uncomment means remove the hash `#` at the beginning of the line.
-- If you need more than one Starr app, add another `[[header]]` for that app.
-- Example with two Radarrs:
+When adding a second (or third+) instance to the __config file__, you just
+add another `[[header]]` <font color="gray">ex. `[[sonarr]]`</font> and the
+`url`/`api_key`/etc under it. When adding a second instance to the __environment
+variables__, you must increment the `0` to a `1`. And to a `2` if you have 3
+instances. There is no limit to the number of supported instances. This notation
+works for all starr apps, folders, command hooks, and web hooks. Anything that [has
+a header](https://github.com/Unpackerr/unpackerr/blob/main/examples/unpackerr.conf.example#L87)
+with double brackets `[[..]]` can be repeated as many times as you'd like.
