Dotfiles are plain text configuration files. They get their name because such files often begin with a dot - e.g., .bashrc.

I’ve found it useful to keep all my configuration files in a GitHub repo. This allows me to easily sync my configuration to any computer I work on.

In addition to using the repo to ensure that I always have my aliases and zsh config on any of my systems, I also find that it’s a great way to share my config with folks who ask about it when pairing.
