+# github-release
+
+An action used to publish GitHub releases for `wasmtime`.
+
+As of the time of this writing there's a few actions floating around which
+perform github releases but they all tend to have their set of drawbacks.
+Additionally nothing handles deleting releases which we need for our rolling
+`dev` release.
+
+To handle all this this action rolls-its-own implementation using the
+actions/toolkit repository and packages published there. These run in a Docker
+container and take various inputs to orchestrate the release from the build.
+
+More comments can be found in `main.js`.
+
+Testing this is really hard. If you want to try though run `npm install` and
+then `node main.js`. You'll have to configure a bunch of env vars though to get
+anything reasonably working.
