1. create an account 2. define the functions your SaaS supports and the parameters necessary to run them 3. define the contextual data that may be needed to process the user's request 4. Add drop-in JS script to your site. Set the current user's contextual data, and connect the script's output to your site's functions. Tell the script to show the Rehance UI where it makes sense in your site.

The script will display the UI when you tell it to, it will process user requests, convert them into functions you support, and run the functions if the user approves.
