+During the build pipeline, it pulls the latest Astro template from the `fcos-suite-astro` repo and then replaces the `public` and `src/pages` folders. You can do the same thing locally by running the `build.sh` script in the root folder.
+
+1. Make sure you have `rsync` installed locally on your system
+2. Run `build.sh`
+3. Create a `.env` file (you can just duplicate the example file)
+4. Run `npm install`
+5. Run `npm run dev`
