The individual Project page provides a detailed overview of a Project's work, including a table of all Stories in the Project as well as a breakdown of Story types, information on recent updates, and Project-specific reporting.
You can get to the individual Project page by clicking on it's title on the Projects page.
From this page you can also edit the Project, add additional followers, archive the Project, and change the Project description or abbreviation (used on Story cards). You can also use the Filter Stories as a search tool to surface specific Stories within the Project.
The Project also includes a reports tab that features a Reports section to track the Project team's average velocity over the last three months of iterations. (More on defining Iterations here.)
