I am glad you are trying out our product.
I would like to recommend you the following two pieces from our online docs:
1. This one explains different concepts like users, sessions - http://docs.telerik.com/platform/analytics/getting-started/analytics-concepts
2. This one explains what is the installation ID and how it is advised to use it - http://docs.telerik.com/platform/analytics/integration/installations/installation-id
I hope you will find them useful. Should you have any questions, issues or just want to share some feedback, please don't hesitate to contact us.
