+## Layer0
+You can deploy your Astro project using the steps in the following sections.
+
+### Create the Astro Site
+If you don't have an existing Astro site, you can create one by running:
+
+```bash
+# Make a new project directory, and navigate directly into it
+$ mkdir my-astro-project && cd $_
+
+# prepare for liftoff...
+$ npm init astro
+
+# install dependencies
+$ npm install
+
+# start developing!
+$ npm run dev
+
+# when you're ready: build your static site to `dist/`
+$ npm run build
+```
+
+### Add Layer0
+
+```bash
+# First, globally install the Layer0 CLI:
+$ npm i -g @layer0/cli
+
+# Then, add Layer0 to your Astro site:
+$ 0 init
+```
+
+### Update your Layer0 Router
+
+Paste the following into routes.ts:
+
+```js
+// routes.ts
+import { Router } from '@layer0/core'
+
+export default new Router()
+  .get('/:path*/:file.:ext(js|css|png|ico|jpg|gif|svg)', ({ cache, serveStatic }) => {
+    cache({
+      browser: {
+        // cache js, css, and images in the browser for one hour...
+        maxAgeSeconds: 60 * 60,
+      },
+      edge: {
+        // ... and at the edge for one year
+        maxAgeSeconds: 60 * 60 * 24 * 365,
+      },
+    })
+    serveStatic('dist/:path*/:file.:ext')
+  })
+  .match('/:path*', ({ cache, serveStatic, setResponseHeader }) => {
+    cache({
+      // prevent the browser from caching html...
+      browser: false,
+      edge: {
+        // ...cache html at the edge for one year
+        maxAgeSeconds: 60 * 60 * 24 * 365,
+      },
+    })
+    setResponseHeader('content-type', 'text/html; charset=UTF-8')
+    serveStatic('dist/:path*')
+  })
+```
+
+You can remove the origin backend from `layer0.config.js`:
+
+```js
+module.exports = {}
+```
+
+### Deploy to Layer0
+
+To deploy your site to Layer0, run:
+
+```bash
+# Create a production build of your astro site
+$ npm run build
+
+# Deploy it to Layer0
+$ 0 deploy
+```
