+# Cloudflare Workers
+
+Source code for our [Cloudflare
+Workers](https://developers.cloudflare.com/workers/).
+
+Each worker is a self contained directory with its each `package.json`.
+
+## Deploying
+
+* Switch to a worker directory, e.g. `cd health-check`.
+
+* Install dependencies (if needed) with `yarn`
+
+* Login into wrangler (if needed) using `yarn wrangler login`
+
+* Deploy! `yarn wrangler publish`
+
+Wrangler is the CLI provided by Cloudflare to manage workers. Apart from
+deploying, it also allows us to stream logs from running workers by using `yarn
+wrangler tail`.
+
+## Creating a new worker
+
+Copy paste an existing one. Unironically this is a good option because the
+Cloudflare template has a lot of unnecessary noise, but if really do want to
+create one from scratch, use `npm create cloudflare@latest`.
+
+To import an existing worker from the Cloudflare dashboard, use
+
+```sh
+npm create cloudflare@2 existing-worker-name -- --type pre-existing --existing-script existing-worker-name
+```
