+
+==============================
+Adding the fields to the Admin
+==============================
+
+By default, Django Categories adds the fields you configure to the model's Admin class. If your ModelAdmin class does not use the ``fieldsets`` attribute, the configured category fields are simply appended to the bottom the fields. If your ModelAdmin uses the ``fieldsets`` attribute, a new fieldset named ``Categories``, containing all the configured fields is appended to the fieldsets. You can override or alter this behavior with the :ref:`ADMIN_FIELDSETS` setting.
+
+ADMIN_FIELDSETS allows you to:
+
+* Prevent Django Categories from adding the fields or fieldsets to a model's ModelAdmin class.
+* Change the name of the fieldset (from the default: "Categories")
+* Change the placement of the fieldset (from the default: bottom)
+
+Preventing fields in the admin class
+====================================
+
+If you don't want Django Categories to add any fields to the admin class, simply use the following format::
+
+    CATEGORIES_SETTINGS = {
+        'ADMIN_FIELDSETS': [
+            'app.model': None,
+        ]
+    }
+
+Changing the name of the field set
+==================================
+
+To rename the field set, use the following format::
+
+    CATEGORIES_SETTINGS = {
+        'ADMIN_FIELDSETS': [
+            'app.model': 'Taxonomy',
+        ]
+    }
+
+Putting the field set exactly where you want it
+===============================================
+
+For complete control over the field set, use the following format::
+
+    CATEGORIES_SETTINGS = {
+        'ADMIN_FIELDSETS': [
+            'app.model': {
+                'name': 'Categories',
+                'index': 0
+            },
+        ]
+    }
