All apps should include an about page as a way to engage with your users. If you’re part of DVLUP this is a basic requirement of most challenges. The about page should describe your app, you the author & include your contact details in case your users want to provide any feedback. Also it can be used to showcase your other apps. I earlier wrote an tutorial on using app catalog using Telerik Controls.
As the controls are not free, you all may not have access to it. In this tip I am providing you the source code of the project without using Telerik Controls. You can refer the previous post for the steps.
