 shell with all required tools – you don't need to run `npm install` anymore.
+Run `nix build ".#angestoepseltSiteEnv" -o .dev` to get a running Node

 When Node dependencies are updated (this will change `package.json`), make sure

 The flake also contains a second package for building the production output:
 
 ```shell
-nix build .#angestoepselt-site
+nix build # Will create an output derivation in 'result'
 ```
 
 The final derivation contains a `www` folder that can be served.
