# git config
> Manage custom configuration options for Git repositories.
> These configurations can be local (for the current repository) or global (for the current user).
> More information: <https://git-scm.com/docs/git-config>.
- Globally set your name or email (this information is required to commit to a repository and will be included in all commits):
`git config --global {{user.name|user.email}} "{{Your Name|email@example.com}}"`
- List local or global configuration entries:
`git config --list --{{local|global}}`
- List only system configuration entries (stored in `/etc/gitconfig`), and show their file location:
`git config --list --system --show-origin`
- Get the value of a given configuration entry:
`git config alias.unstage`
- Set the global value of a given configuration entry:
`git config --global alias.unstage "reset HEAD --"`
- Revert a global configuration entry to its default value:
`git config --global --unset alias.unstage`
- Edit the local Git configuration (`.git/config`) in the default editor:
`git config --edit`
- Edit the global Git configuration (`~/.gitconfig` by default or `$XDG_CONFIG_HOME/git/config` if such a file exists) in the default editor:
`git config --global --edit`
