 - If you want to contribute for a different platform (python, go, etc.) we're happy to help! It should probably live in a different repo until it's close to `1.0`, but once it's near completion we're happy to maintain it here if you would like. Discuss in [selfie#85](https://github.com/diffplug/selfie/issues/85), but also feel free to open a PR with any ideas you have.
 
 Pull requests are very welcome, preferably against `main`.
