On the Start page drop-down menu, select the webpage that uses the chrome control. Make sure that the SharePoint Add-in project is set as the startup project. Select the F5 key.

Is the add-in web the same as the host web?
The special website to which the add-in is deployed is called an add-in web. The website to which the add-in is installed is called the host web. Although the add-in web has its own isolated domain, it is in the same site collection as the host web.
How to add add-in icon to chrome control?

How is the host URL obtained in SharePoint?
The remote web application obtains the host web URL from a query string parameter that SharePoint adds to the URL of the start page when it launches the add-in. Because SSL is being used, this query string is encrypted as it goes across the Internet to the remote web application.
