As a user, I would like descriptions for key features available in the UI.

For features and functionality that are relevant to the view I am in that tell me:

• What is it?
• What should I know about it? / What does it do for me?
• What is is required for? (i.e. you have to create a workspace using a template)
• Where do I make changes to it?

For instance:

• Templates
• Workspaces
• Resource
• Agent

These could be info icon pop overs, collapsible descriptions, etc.
