    2121Databases can have any alias you choose. However, the alias
    2222``default`` has special significance. Django uses the database with
    23 the alias of ``default`` when no other database has been selected. If
    24 you don't have a ``default`` database, you need to be careful to
    25 always specify the database that you want to use.

     46If the concept of a ``default`` database doesn't make sense in the context
     47of your project, you need to be careful to always specify the database
     48that you want to use. Django requires that a ``default`` database entry
     49be defined, but the parameters dictionary can be empty if it will not
     50be used.

     52The following is an example ``settings.py`` snippet defining two non-default
     53databases, with the default entry intentionally left empty.
