Tracking changes to scripts in my ~, such as ~/.zshrc.
The .gitigore excludes all files recursively, so anything you want to track needs to be added with a negation. For example, !.zshrc.
It's also common to have a global ~/.gitignore, which obviously conflicts with this one. To get around that, just rename it to ~/.gitignore.global and then tell git about it:
git config --global core.excludesfile ~/.gitignore.global
