Niv ? Npins?

[jd1t25]

Hi , I am new and still learning,
Following the wiki , during "nix-build" it throws error

in default.nix
sources ? import ./nix/sources.nix,
nix/sources.nix': No such file or directory

before that we run npin
nix-shell -p npins --run "npins init --bare; npins add github nixos nixpkgs --branch nixos-23.11"

tree npins

npins
├── default.nix
└── sources.json

which clearly doesn't what sources.nix

after researching on its github , i found its alternative niv
then reading its wiki and running this
nix-shell -p niv --run "niv init; niv add NixOS/nixpkgs -n nixpkgs -b nixos-23.11"

tree niv

nix
├── sources.json
└── sources.nix

Either use niv or npin
( Or i mess up something big , and this pr just a mistake)

Ah yes, thanks a lot - I missed that spot when changing things from niv to npins.
