The supported frameworks documentation might be confusing for people interested in knowing about compatibility with datastores for the following reasons:
The "instance details" section still lists ActiveRecord 2/3/4 as supported, which is incorrect
The existence of separate "databases" and "instance details" sections to outline datastore compatibility is confusing
The "instance details" section has a "gem databases" table which is confusing. The term "gem databases" is incorrect. Perhaps there was once an intention to list individual gems used for datastore client usage. The NoSQL stores Mongo and Redis are listed both in this table and in the one in the "databases" section. Given that there is only a single supported gem for each of these datastores, moving the info into the "databases" section would make the most sense.
