+## setup (nix)
+
+u has a nix flake you can use - just add `u.url = "git+https://git.n2.pm/NotNite/u.git";`. both the server (`u`) and client (`u-upload`) are available as packages.
+
+you can also use the NixOS module (`u.nixosModule`) and enable `services.u`.
+
 ## using u
 
 examples are with curl - you can (obviously) use any HTTP client.
