To use:

• These two files can live in eg ~/Documents/civicrm-docs/scripts/scheduled-jobs
• cd ~/Documents/civicrm-docs/scripts/scheduled-jobs && npm install (now the dependencies are installed)
• cd ~/Sites/civicrm.dev (now you're in a working CiviCRM site)
• node ~/Documents/civicrm-docs/scripts/scheduled-jobs/main.js (run main.js while you're in the site, so cv can bootstrap site for API)
• Will output .md which you can use to update the page as shown in the PR

Paths above are not significant, except to demonstrate that the docs repo and the civi site used to generate are decoupled and you only need a cv-capable CiviCRM install to update the docs.

Output is as below.
