There's a lot of direction here towards storing your config in source control, just make sure you're OK with what you're storing and assure yourself that if a stranger were to get ahold of your config that nothing could be exploited with that config data.
For example, don't store your secret API access keys in your config in your git repository. I've seen plenty private repositories get forked by contractors (or inexperienced friends/developers) and somehow get published publicly or leaked. It's easiest to avoid all of this by having other means of sharing that sensitive data.
