* Enable flakes in Nix by e.g. adding ``experimental-features = nix-command flakes`` to ``nix.conf`` (for example ``~/.config/nix/nix.conf``).
* Enter the development shell by running ``nix develop git+https://github.com/m-labs/artiq.git``, or alternatively by cloning the ARTIQ Git repository and running ``nix develop`` at the root (where ``flake.nix`` is).
* You can then build the firmware and gateware with a command such as ``$ python -m artiq.gateware.targets.kasli``. If you are using a JSON system description file, use ``$ python -m artiq.gateware.targets.kasli_generic file.json``.
* Flash the binaries into the FPGA board with a command such as ``$ artiq_flash --srcbuild -d artiq_kasli -V <your_variant>``. You need to configure OpenOCD as explained :ref:`in the user section <configuring-openocd>`. OpenOCD is already part of the flake's development environment.
* Flash the binaries into the FPGA board with a command such as ``$ artiq_flash --srcbuild -d artiq_kasli/<your_variant>``. You need to configure OpenOCD as explained :ref:`in the user section <configuring-openocd>`. OpenOCD is already part of the flake's development environment.
* Check that the board boots and examine the UART messages by running a serial terminal program, e.g. ``$ flterm /dev/ttyUSB1`` (``flterm`` is part of MiSoC and installed in the flake's development environment). Leave the terminal running while you are flashing the board, so that you see the startup messages when the board boots immediately after flashing. You can also restart the board (without reflashing it) with ``$ artiq_flash start``.
* The communication parameters are 115200 8-N-1. Ensure that your user has access to the serial device (e.g. by adding the user account to the ``dialout`` group).
