Once you have added the indexes to make those pages fast, just validate your work with MongoProc. If everything is working properly, you should be able to start the blog by typing: This homework is meant to give you practice using the “package. This dataset holds the same type of data as last week’s grade collection, but it’s modeled differently. The blog stores its data in the blog database in two collections, users and sessions.
