-Cross-compiling Rust for the Raspberry PI
+Cross-compiling Rust for the Q7S
 ======
 
+# Build with `cargo`
+
+Build debug image: 
+
+```sh
+cargo build --target armv7-unknown-linux-gnueabihf
+```
+
+You can then transfer the application with `scp`. It is recommended to use
+the `q7s-cp.py` utility which is part of the
+[EIVE OBSW script folder](https://egit.irs.uni-stuttgart.de/eive/eive-obsw).
+
+If you use this script, you can use the `deploy-q7s.sh` script to deploy the
+binary conveniently.
+
 # Prerequisites
 
-1. Install standard library
+1. Install rust on your development machine using `rustup`
+
+   ```sh
+   curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
+   ```
+
+2. Install standard library for target architecture
 
 	```sh
 	rustup target add armv7-unknown-linux-gnueabihf
    ```
 
-2. Install a cross-compile toolchain and add it to your path.
-   You can download one built with crosstool-ng from
-   [here](https://www.dropbox.com/sh/hkn4lw87zr002fh/AAAO-HxFQzfmmPQQ9KVmoooGa?dl=0).
+3. Install a cross-compile toolchain for the Cortex-A9 target and add it to your path.
+   It is recommended to take the same toolchain used to compile the Q7S primary OBSW.
+   See the [dedicated README](https://egit.irs.uni-stuttgart.de/eive/eive-obsw)
+   for more details and download links.
+
+4. Install `sshpass`
+
+   ```sh
+   sudo apt-get install sshpass
+   ```
+
+5. Specify the ssh password as the `SSHPASS` variable
+   
+   ```sh
+   export SSHPASS="<sshPassword>"
+   ```
