Command Line Interface


The best way to get started with the CLI is to read use our Interactive Walkthrough. That will take you down the right path depending on your operating system, experience with the command line, etc, and will get your CLI configured.

If you just want to download the CLI manually and work out how to use it, you can download and install it from GitHub. However, please note that we ask that you work through the Interactive Walkthrough before opening any support requests.

Upgrading from pre-v3

If you have a previous version of the CLI and want to upgrade, please read these instructions.

Basic usage

Run the help subcommand to get the full list of available commands.
