+`Amazon DocumentDB (with MongoDB compatibility) <https://docs.aws.amazon.com/documentdb/latest/developerguide/what-is.html>`__
+is a fast, reliable, and fully managed database service. Amazon DocumentDB makes it easy
+to set up, operate, and scale MongoDB-compatible databases in the cloud.
+With Amazon DocumentDB, you can run the same application code and use the same drivers
+and tools that you use with MongoDB.
+
+Version Information
+-------------------
+
+Amazon DocumentDB supports MongoDB v4.0 and MongoDB v5.0. These versions don't 
+support all the newer features and functionality in the versions of MongoDB available
+on `MongoDB Atlas. <https://www.mongodb.com/docs/atlas/>`__
