+## Contributing
+
+### Coding
+
+This crate aims to be of higher quality vs quantity.
+This means that the bar for what gets merged is maybe higher than some want to bother with.
+Please run the clippy checks along with nightly cargo formatting, and check that the CI checks pass.
+
+Any contributions are welcome though, just mark the PR as editable by maintainers.
+That way even if you don't feel like acting out on the feedback, the improvements will most likely eventually find their way back to here.
+
+### Other
+
+Alternatively if you don't feel like coding, creating GitHub issues for wrong behavior would be very welcome.
+Additionally, figuring out the actual data types and inheritance models, and improving the docs would really help with development!
+Also just starring this GitHub repository helps with motivation for more work on this crate that serves other projects as well.
