 ## Nix commands
 
-Start nix shell before anything.
+Humpback-DDS firmware is packaged using the [Nix](https://nixos.org) Flakes system. Install Nix 2.4+ and enable flakes by adding ``experimental-features = nix-command flakes`` to ``nix.conf`` (e.g. ``~/.config/nix/nix.conf``). 
+
+Once you have Flakes enabled, you can use ``nix build`` to build the firmware.
+
+Alternatively, you can develop and build it within Nix shell:
 ```shell
-nix-shell
+nix develop
+python fpga/fpga_config.py
+cargo build --release
 ```
 
 **(For users who had completed the [networking setup](##networking-setup-for-first-time-user))** Flash firmware onto STM32 NUCLEO-H743ZI2 using OpenOCD.
