 Development instructions
 ------------------------
 
-Configure Nix channels:
-
-```shell
-nix-channel --add https://nixbld.m-labs.hk/channel/custom/artiq/fast-beta/artiq-fast
-nix-channel --update
-```
-
-Notes:
-
-- Rust Pitaya does not depend on ARTIQ but uses some packages available in the ARTIQ channel.
-- If you are using Nix channels the first time, you need to be aware of this bug: https://github.com/NixOS/nix/issues/3831.
-
 Pure build with Nix and execution on a remote JTAG server:
 
 ```shell
-nix-build -A rust-pitaya-jtag
+nix build .#rust-pitaya-jtag
 ./remote_run.sh
 ```
 
 Impure incremental build and execution on a remote JTAG server:
 
 ```shell
-nix-shell
+nix develop
 cd src
 gateware/rust-pitaya.py -g ../build/gateware  # build gateware
 make                                          # build firmware

 Notes:
 
-- This is developed with Nixpkgs 20.09, and the ``nixbld.m-labs.hk`` binary substituter can also be used here (see the ARTIQ manual for the public key and instructions).
 - The impure build process is also compatible with non-Nix systems.
 - If the board is connected to the local machine, use the ``local_run.sh`` script.
