+Your local copy of the site should be available by this URL: http://localhost:4567
+
+
+## Deploy the Site to GitHub Pages
+
+This example describes the deployment process of our official documentation 
+site,
+http://parallels.github.io/vagrant-parallels/docs/. You will need 
+write permissions for the GitHub repo which you want to deploy to. 
+
+Make sure your current working directory is `website/docs/`. Then clone 
+"gh-pages" branch from the target repo to `./build` directory.
+```
+$ git clone -b gh-pages https://github.com/Parallels/vagrant-parallels ./build
+```
+
+If you want to deploy to your fork, put the URL of your fork repo instead:
+```
+$ git clone -b gh-pages https://github.com/<YOUR_USER>/vagrant-parallels ./build
+```
+
+Then run this command to build static pages with Middleman and deploy them to
+the repo you've cloned before:
+
+```
+$ bundle
+$ bundle exec middleman deploy --build
+```
+
+The site should be available on GitHub: http://parallels.github.io/vagrant-parallels/docs/
+(or `http://<YOUR_USER>.github.io/vagrant-parallels/docs/`)
