Secret Config?

[muizidn]

Wouldn't it be safe if you just provide template. You can use YAML document or equivalent to provide list of needed variable to configure for every contributor. But if this doesn't relate, you can ignore this.
From my understanding that there is different environment per project. You can specify if that is PRODUCTION or DEVELOPMENT. So you may ignore the PRODUCTION config and commit DEVELOPMENT one. If you feel so sure, you can add default values in configuration you committed.
