I have created an app named “MyFirstSharePointHostedApp”
which I have uploaded in the app catalog. I have a site named http://c4968397007/sites/Vijai/ in
which I am going to add the app that I have uploaded in the app catalog. To add
an app you should be the member of a site owners group. Navigate to the
SharePoint site http://c4968397007/sites/Vijai/.
Click on Site Contents which is
available in the quick launch bar. Click on add an app.
Under Apps you can add click on “MyFirstSharePointHostedApp” app.
Click on Trust it.
App is added successfully to
the site from app catalog.
