How to Contribute

Welcome contributions

• If the project is not translated into your language, you can propose a translation.

• If you've encountered a problem or bug that you've solved, the patch will be very welcome !

Unwelcome contributions

Please do not propose a Merge Request before opening first an issue on gitlab, if you want to add new feature, new devices, etc.

Maintaining a driver library is an impossible task if you don't own the device. If the device or the feature you propose is not in the Roadmap of the GRAP company, it will be refused, to avoid rising technical debt.

In that case, do not hesitate to fork the project, to implement your change in a dedicated branch.
