+
+   By adding proxy address for browsersync.example.lndo.site and storybook.example.lndo.site that point to the ports needed, those applications can be accessible by navigating to the addresses without the ports from outside the container services. 
+   
+   Since we are using proxies instead of forwarding ports directly, multiple projects can make use of these ports simultaneously.
+   ```yaml
+   proxy:
+      appserver:
+         - example.lndo.site
+         - browsersync.example.lndo.site:32778
