Where do I find documentation/more information concerning a data set?

To access documentation, locate and select the link from the Projects Supported page for the project that you would like additional documentation. From the project page, locate and select the grey tab that says “documentation,” (it is the grey tab, typically located in the middle of the page). If the documentation is product specific, continue to navigate to the specific product landing page where you can access it if it is available, note that a missing tab on the product page indicates that there is no documentation specific to that product.
