# Credits

> The projects tidy ports code from, and the licenses they carry.

tidy is a port. Almost none of the hard thinking in it is original, and all of it is someone else's work under a license that allowed the port.

The authoritative list is [`docs/credits.md`](https://github.com/lukeed/tidy/blob/main/docs/credits.md) in the repository, which names versions and copyright holders.
