# Command-line tools

Develop and customize your projects in Terminal.

## Overview

You can use command-line tools to perform some actions in Terminal without running Xcode.
For example, you can develop your open source or cross-platform projects,
notarize your macOS software, automate your builds, implement continuous integration,
and apply specific settings to your projects.
