 Alternatively you may want to install VSCode on your host. We will explore how
 to integrate VSCode installed via **Flatpak** with Distrobox.
 
-Note that this integration process is inspired by the awesome project [toolbox-vscode](https://github.com/owtaylor/toolbox-vscode)
-so many thanks to @owtaylor for the heavy lifting!

-We need not to deploy a configuration for our container. We should create one for
