Context Sensitive Help

Catalyst also provides context sensitive help when you encounter an error during a CLI command execution. Catalyst will not only specify the reason behind the error, but it will also provide you help with the actions you can take to rectify or prevent the error, as well as a help link to the documentation of the particular action.

This is discussed in the CLI Context Sensitive Help page in detail, which also includes a list of possible errors that you could encounter during each of your command executions.
