 If you want to change or extend n8n you have to make sure that all the needed
 dependencies are installed and the packages get linked correctly. Here's a short guide on how that can be done:
 
+### Dev Container
+
+If you already have VS Code and Docker installed, you can click [here](https://vscode.dev/redirect?url=vscode://ms-vscode-remote.remote-containers/cloneInVolume?url=https://github.com/n8n-io/n8n) to get started. Clicking these links will cause VS Code to automatically install the Dev Containers extension if needed, clone the source code into a container volume, and spin up a dev container for use.
