+# VMP Debian RootFS
+
+This subdirectory contains the scripts and configuration files to build a Debian
+root filesystem with the complete VMP stack installed.
+
+We use [rootfsbuilder](https://github.com/hmelder/rootfsbuilder) to build the
+root filesystem. By default, a squashfs image is created, but it is also possible
+to create a tarball by adding `"tarball_type": "tar.gz"` to the JSON configuration.
+
+## Building the root filesystem
+
+Obtain the `rootfsbuilder` tool by building it from source. More
+information about the tool and the build process can be found in the
+projects README.
+After that, run the following command to build the root filesystem:
+
+```bash
+sudo ./setup.sh # This will create payload.tar
+sudo rootfsbuilder bookworm-amd64.json
+```
+
+The payload contains a post install script that builds the Objective-C environment (libobjc2, libdispatch (Grand Central Dispatch), gnustep-base (Foundation)). If everything goes well, you now have a squashfs image in
+the current working directory.
+
+## Customizing the root filesystem
+
+You can add additional files to the root filesystem by adding them to the
+payload directory. The files will be copied to the root filesystem during the
+build process.
+
+If you want to change the release or distribution, you can modify the
+build configuration JSON file.
