Add French language support and user guide

[Oum-Hanouna]

Hello Simon,

Thank you for this great free app. I haven’t been able to use it yet because I don’t know how to operate it.

I would like to kindly ask if you could add French language support in the user interface. Also, a simple French user guide would be very helpful for French-speaking users like me.

Thank you for your consideration!

The app is not adapted for supporting multiple languages right now and there is no immediate plans to implement that. I will keep french top of mind whenever that changes however!
