Guide to the Settings page

From the screenshot below you can see a typical view of the Settings page.  From here you can Check for Updates manually, and toggle on/off auto updates. 

Under Current Content it shows what Group you are currently viewing, and from the Switch Content button you can choose a different Group if available. 

The last four sections are more specific in terms of usage, availability, and device.  Integrations, Language, Storage and Lead Capture are more advanced functions that may not be available in all instances.
