+## Build for the Q7S target root filesystem with `yocto`
+
+The EIVE root filesystem will contain the EIVE OBSW and the Watchdog component.
+It is currently generated with `yocto`, but the tool can not compile the primary
+OBSW due to toolchain version incompatibility. Therefore, the OBSW components
+are currently compiled using the toolchain specified in this README (e.g. installed by Vivado).
+
+However, it is still possible to install the two components using yocto. A few helper files were
+provided to make this process easier. The following steps can be used to install the OBSW
+components and a version file to the yocto sources for the generation of the complete EIVE root
+file system image. The steps here are shown for Ubuntu, you can use the according Windows
+helper scripts as well.
+
+1. Copy the `q7s-env.sh` script to the same layer as the `eive-obsw`.
    
    ```sh
-   cd cmake-build-debug-q7s
+   cp scripts/q7s-env.sh ..
+   cd ..
+   ./q7s-env.sh
+   q7s-make-release.sh
+   ```
+
+2. Compile the OBSW components in release mode
+
+   ```sh
+   cd cmake-build-release-q7s
    cmake --build . -j
    ```
 
+3. Make sure the [`q7s-yocto`](https://egit.irs.uni-stuttgart.de/eive/q7s-yocto)
+   repository or the [`q7s-package`](https://egit.irs.uni-stuttgart.de/eive/q7s-package.git)
+   repository and its `q7s-yocto` submodule were cloned in the same directory layer as
+   the `eive-obsw`.
+
+4. Run the install script to install the files into `q7s-yocto`.
+
+   ```sh
+   install-obsw-yocto.sh
+   ```
+
+5. Navigate into the `q7s-yocto` repo and review the changes. You can then add and push those
+   changes.
+
+6. You can now rebuild the root filesystem with the updated OBSW using `yocto`. This probably needs
+   to be done on another machine or in a VM. The [`q7s-yocto`](https://egit.irs.uni-stuttgart.de/eive/q7s-yocto)
+   repository contains details on how to best do this.
