+## Releases
+
+Releases are to be created and managed through
+[GitHub Releases](https://github.com/bjuppa/com-plain-date/releases).
+
+New releases are automatically published to
+[deno.land](https://deno.land/x/complaindate) with a
+[GitHub Webhook](https://github.com/bjuppa/com-plain-date/settings/hooks) and to
+[npm](https://www.npmjs.com/package/complaindate) with a
+[GitHub Action](https://github.com/bjuppa/com-plain-date/actions).
+
+## Testing the package
+
+There's a script (using [dnt](https://github.com/denoland/dnt)) that generates
+an npm package from the current code into [the `npm/` directory](/npm):
+
+```sh
+# Version tag is not required for local testing
+deno run -A scripts/build_npm.ts
+```
+
+If you have an npm project setup locally for testing, you may install the built
+package using a local path:
+
+```sh
+npm install path/to/com-plain-date/npm
+```
