 ## Managing NixOS configurations
 
-NixOS relies on the `NIX_PATH` environment variable to locate `nixpkgs`, which defaults to using channels.
-To instead use a `nixpkgs` version managed by `npins`, one can manually override this environment variable on system rebuilds:
+NixOS defaults to using channels to locate `nixpkgs`.
+You can instead pin a version using `npins` from the `system.nix` entrypoint (available since 26.05):

+import "${sources.nixpkgs}/nixos" {

 ```bash
 sudo NIX_PATH="nixos-config=configuration.nix:nixpkgs=$(nix-instantiate --raw --eval npins -A nixpkgs.outPath)" nixos-rebuild switch
 ```
 
+If you use npins with `system.nix`, disable channels in your configuration:
