App Signing

@ryan_harg @egon0

I think we need to talk about App signing. I have no idea how this works or which implications this has, but in order to publish something on the playstore I need to give them information and I am like hääää?

(sorry for german)

So, how to sign our Apps? If we have the keys, they should go to our Bitwarden (tell me if you need access)
