+## Requirements:
+
+### Known Issues
+Ubuntu 22.04 has some version issues with the compile toolchain, consider using a newer version or other distribution or docker. Or solve the issue and add it here.
+
+### Steps 
+1. `cmake`
+2. `arm-none-eabi-gcc arm-none-eabi-gcc arm-none-eabi-binutils arm-none-eabi-gdb arm-none-eabi-newlib`
+3. `doxygen` 
+4. `graphviz`
+5. `rustup`  || Install using your packet manager or alternatively use the rust install script:  `curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh`
+
+
+
+6. At last: Satisfy Rust requirements 
+
+```sh
+cd ../mission_rust
+cargo update 
+rustup toolchain install nightly
+rustup component add rust-src --toolchain nightly-x86_64-unknown-linux-gnu
+rustup override set nightly
+cargo build -Z build-std
+```
 
 ## Build the FSBL
 
 FSBL is the First Stage Boot Loader and prepares the CPU and FPGA configuration for booting up the Second Stage Bootloader and finally the flight software. 
 
+```sh
+cd lib/sw_apps/zynq_fsbl/src
+make BOARD=zed SHELL=/bin/bash
