The first category that appears on the left upper corner of the page is the Summary of my projects. It indicates the total number of your projects as well as the number of sources added to those projects.
Below these figures, two boxes indicate the percentage of sources that have been tagged within the projects you are part of, and the percentage of sources that have been tagged and validated during the quality and control process (see section on Tagging).
If you are a new user on the platform, the categories detailed above will appear but they will mainly be empty. They will populate as your activity on DEEP increases.
