Specify that table names need to be capitalized on the "Getting started" page.

Could save new users a bit of debugging time in the future.

It would be even better to check correct capitalization when creating a table and provide an informative error.

Currently, an uninformative error is thrown in Matlab:

Error using containers.Map/subsref
The specified key is not present in this container.

But the table is still created behind the scenes, even though the error was thrown. So when the user tries again, a different error is thrown:

Error using mym
Table 'mouse' already exists

This is pretty confusing.

Additionally, we should mention that after errors occur, it may become necessary to dj.close() and clear classes so that everything could be properly reloaded.
