+We have two cloudflare workers that let us serve some assets of this repo
+from Cloudflare.
+
+* `open-source-website-assets` is used for `install.sh`
+* `docs-proxy` is used for `https://zed.dev/docs`
+
+On push to `main`, both of these (and the files they depend on) are uploaded to Cloudflare.
+
+### Testing
+
+You can use [wrangler](https://developers.cloudflare.com/workers/cli-wrangler/install-update) to test these workers locally, or to deploy custom versions.
