When configuring Git using `git config` command, the following scopes are available:
- `--system` scope applies to all users on specific host. System configuration is located in `/etc/gitconfig`
- `--global` scope means that configuration is applied only to user's account. Global configuration is located in `~/.gitconfig`.
- `Local (no flag)` scope applies only to specific git repository. Local configuration is located in `.git/config` inside the repo.
