## Installing Your Files

Here is how to install your files:

```bash
git clone $YOUR_REPOSITORY dotfiles # clone your files
cd dotfiles # change directory

Link commands support an optional extended configuration. In this type of

When `glob: True`, Dotbot uses [glob.glob](https://docs.python.org/3/library/glob.html#glob.glob) to resolve glob paths, expanding Unix shell-style wildcards, which are **not** the same as regular expressions; Only the following are expanded:
