Add Contributing.md or other resource for potential contributors
At the moment, there are several checks on commits that are not documented anywhere (?). It would be nice to list these requirements to prevent unnecessary confusion & CI failures.
Additionally, such a document would be a good place to mention code style guidelines (if any), etc.
It might not be documented in this repo, but the same rules for general OpenWrt contributions still apply here: https://openwrt.org/submitting-patches
Yes, this
https://github.com/openwrt/omcproxy/blob/11e45f6cfe105fb3bacc5c38face79f2aa619984/.github/workflows/formal.yml#L12
hints some general rules as well, but I wasn't aware of these tbh.
May I suggest adding a little section into the README.md? Something like
## Contributing
omcproxy is part of the OpenWrt Project, and as such, its contribution guidelines apply. You can find them [here](https://openwrt.org/submitting-patches).
