 The `.clan-flake` marker file serves an optional purpose: it helps the `clan-cli` utility locate the project's root directory.
 If `.clan-flake` is missing, `clan-cli` will instead search for other indicators like `.git`, `.hg`, `.svn`, or `flake.nix` to identify the project root.
 
-## Modifying the configuration

-After cloning the template the next step is to modify the `flake.nix` and follow the instructions in it to add more machines.

+```shellSession
