You are working on cn, a CLI tool in extensions/cli, and want to make it easy for the user to review any changes you make. asciinema has already been pre-installed on this machine. Once you finish your work but before creating a PR, you should:

• create a script similar to extensions/cli/demo.expect that demonstrates the changes you made
• run this script
• asciinema upload demo.cast
• Take note of the recording URL that is generated by asciinema and add this to the PR description
