-Write a 404 (page not found) view
-=================================
-
-When you raise :exc:`~django.http.Http404` from within a view, Django
-will load a special view devoted to handling 404 errors. It finds it
-by looking for the variable ``handler404`` in your root URLconf (and
-only in your root URLconf; setting ``handler404`` anywhere else will
-have no effect), which is a string in Python dotted syntax -- the same
-format the normal URLconf callbacks use. A 404 view itself has nothing
-special: It's just a normal view.
-
-You normally won't have to bother with writing 404 views. If you don't set
-``handler404``, the built-in view :func:`django.views.defaults.page_not_found`
-is used by default. Optionally, you can create a ``404.html`` template
-in the root of your template directory. The default 404 view will then use that
-template for all 404 errors when :setting:`DEBUG` is set to ``False`` (in your
-settings module). If you do create the template, add at least some dummy
-content like "Page not found".
-
-.. warning::
-
-    If :setting:`DEBUG` is set to ``False``, all responses will be
-    "Bad Request (400)" unless you specify the proper :setting:`ALLOWED_HOSTS`
-    as well (something like ``['localhost', '127.0.0.1']`` for
-    local development).
-
-A couple more things to note about 404 views:
-
-* If :setting:`DEBUG` is set to ``True`` (in your settings module) then your
-  404 view will never be used (and thus the ``404.html`` template will never
-  be rendered) because the traceback will be displayed instead.
-
-* The 404 view is also called if Django doesn't find a match after checking
-  every regular expression in the URLconf.
-
-Write a 500 (server error) view
-===============================
-
-Similarly, your root URLconf may define a ``handler500``, which points
-to a view to call in case of server errors. Server errors happen when
-you have runtime errors in view code.
-
-Likewise, you should create a ``500.html`` template at the root of your
-template directory and add some content like "Something went wrong".
-
 Use the template system
