+# Contributing to Windmill
+
+At this time, we are not seeking outside contribution.
+
+AI has made writing code easy. The hard part, today, is not writing the code, but reviewing it,
+making sure quality stays high, and keeping the product coherent. In that light, unfortunately,
+external code contributions are "donating" the easy part of the job, while creating more of the
+hard work.
+
+With that said, we are happy to accept small, trivially-verified PRs that fix a problem. However,
+we ask that you refrain from submitting low-value PRs (e.g. typo fixes) or PRs that are more than a
+dozen or so lines. Such PRs will be closed with a reference to this guideline.
+
+If you have a big idea you'd like us to consider, feel free to open a
+[feature request](https://github.com/windmill-labs/windmill/issues/new?template=feature_request.md)
+about it.
+
+This policy may change in the future as the project matures. Until then, thank you for your
+understanding.
+
+## What is still very welcome
