 In development mode you will have live-reload functionality and automatic rebuilds of content when you change it. Sadly changes to the configration files will not rebuild the whole site, just restart the docker container to accomplish that.
 
+Alternatively there is a devcontainer that automatically starts when you open the Project in vscode. To run the development server inside the devcontainer use the following command:
+
+    bundle exec jekyll serve --livereload --watch --incremental --host 0.0.0.0 --port "8080"
