Once you've installed the Layer add-on, you can access it as you would any other Google Sheets add-on. All you have to do is:
Open a Google Sheets spreadsheet.
Go to the Extensions menu > Layer > Launch.
This will open Layer on top of your spreadsheet, and you can start using it by creating your first connections to share data or connecting integrations to import data into your Google Sheets.
Let us show you how to make the most of Layer, as well as set up your connections and integrations.
