 ## What is `git-secret`?
 
-`git-secret` is a bash tool to store your private data inside a git repo. How’s that? Basically, it just encrypts, using `gpg`, the tracked files with the public keys of all the users that you trust. So everyone of them can decrypt these files using only their personal secret key. Why deal with all this private-public keys stuff? Well, to make it easier for everyone to manage access rights. There are no passwords that change. When someone is out - just delete their public key, re-encrypt the files, and they won’t be able to decrypt secrets anymore.
