+## Existing Bindings
+
+Certain binding libraries publish the `kopium` output up to crates.io for easier consumption, and this can avoid having to inline generated files in your repo (provided you do not need customization / patches to the output).
+
+The main catalogue library is [metio/kube-custom-resources-rs](https://github.com/metio/kube-custom-resources-rs) which selects crds via features ([don't use all-features](https://mastodon.online/@sebhoss/111356248593690997)).

+Feel free to [edit this file](https://github.com/kube-rs/kopium/edit/main/README.md) to add more.
