+## Static Site
+
+This project includes a simple website generated with the [eleventy](11ty.dev) static site generator and the templates and pages in `/docs-src`. The site is generated to `/docs` and intended to be checked in so that GitHub pages can serve the site [from `/docs` on the master branch](https://help.github.com/en/github/working-with-github-pages/configuring-a-publishing-source-for-your-github-pages-site).
+
+To enable the site go to the GitHub settings and change the GitHub Pages &quot;Source&quot; setting to &quot;master branch /docs folder&quot;.</p>
+
+To build the site, run:
+
+```bash
+npm run docs
+```
+
+To serve the site locally, run:
+
+```bash
+npm run docs:serve
+```
+
+To watch the site files, and re-build automatically, run:
+
+```bash
+npm run docs:watch
+```
+
+The site will usually be served at http://localhost:8000.
