Multiple applications with django

I am studying the Django framework, reading the documentation, but have not found references on how to create more than one application on the same project, where each application has multiple apps. For example, the application Blog, with apps Users, Comments, Posts, ..., implementation and Tasks with the apps Clients, Users, Attachments ... How should I do?

localhost
localhost/blog/ (posts, user, comment, ...)
localhost/tasks/ (task, user, attachment, ...)

<my project>
-- manage.py
-- <project name>
-- -- blog
-- -- -- posts
-- -- -- -- views.py
-- -- -- -- urls.py
-- -- -- -- models.py
...
-- -- tasks
-- -- -- attachments
-- -- -- -- views.py
-- -- -- -- urls.py
-- -- -- -- models.py
...
