What makes a good modal?

Having a clear and descriptive message will explain the window's usage. Users should be able to read the text and understand the message you're trying to tell them and possible actions. Try to match the primary button text with the modal window title because it makes it easier for users to understand the context.

Closing the modal: Always provide a clear close option for users by using a button or an 'x' icon at the top right of the modal.

What is modal dialog?
