 The name of the module follows the same rule as module created from a file: Stem of the directory name, i.e., the directory name, is used as the module name. Again, you could do this as a two-step action using `module` and `use` separately, as explained in the previous section.

 Here we'll create a simple completion module with a submodule dedicated to some Git completions:
 
 1. Create the completion directory

 2. Create an empty `mod.nu` for it

    `touch ($nu.default-config-dir | path join completions mod.nu)`

 3. Put the following snippet in `git.nu` under the `completions` directory
