Description​

The mojo CLI provides all the tools you need for Mojo development, such as commands to run, compile, and package Mojo code. A list of all commands are listed below, and you can learn more about each one by adding the --help option to the command (for example, mojo package --help).

You can check your current version with mojo --version. For version information, see the Mojo changelog.
