A manual that lives inside the product
The Help app is the manual for your environment, laid out in five top-level sections: Getting started, Reference guide, Apps, Setup, and Troubleshooting. Click a tile to see the table of contents for that section, and the Back arrow on any help page returns you to the section index.
Help pages you can favourite
Every help page has a star icon in its toolbar. Click it to add the page to your personal Favourites — useful when you’re learning something new and want a fast way back to the same explanation later.
