+Application loading process
+===========================
+
+Django loads application configurations and models as soon as it starts. Here
+are some common problems you may encounter:
+
+* ``RuntimeError: App registry isn't ready yet.`` This happens when importing
+  an application configuration or a models module triggers code that depends
+  on the app registry.
+
+  For example, :func:`~django.utils.translation.ugettext()` uses the app
+  registry to look up translation catalogs in applications. To translate at
+  import time, you need :func:`~django.utils.translation.ugettext_lazy()`
+  instead. (Using :func:`~django.utils.translation.ugettext()` would be a bug,
+  because the translation would happen at import time, rather than at each
+  request depending on the active language.)
+
+  Executing database queries with the ORM at import time in models modules
+  will also trigger this exception. The ORM cannot function properly until all
+  models are available.
+
+  Another common culprit is :func:`django.contrib.auth.get_user_model()`. Use
+  the :setting:`AUTH_USER_MODEL` setting to reference the User model at import
+  time.
+
+* ``ImportError: cannot import name ...`` This happens if the import sequence
+  ends up in a loop.
+
+  To eliminate such problems, you should minimize dependencies between your
+  models modules and do as little work as possible at import time. To avoid
+  executing code at import time, you can move it into a function and cache its
+  results. The code will be executed when you first need its results. This
+  concept is known as "lazy evaluation".
+
+* ``django.contrib.admin`` will now automatically perform autodiscovery of
+  ``admin`` modules in installed applications. To prevent it, change your
+  :setting:`INSTALLED_APPS` to contain
+  ``'django.contrib.admin.apps.SimpleAdminConfig'`` instead of
+  ``'django.contrib.admin'``.
