 1. Add "dbview" to your INSTALLED_APPS settings like this:
 
-```python
+    ```python
-INSTALLED_APPS = (
+    INSTALLED_APPS = (
-    ...
+        ...
-    'dbview',
+        'dbview',
-)
+    )
-
+    ```
-```

 2. In your models.py create classes which extend dbview.models.DbView
 like this:
 
 
-```python
+    ```python
 
-from django.db import models
+    from django.db import models
-from dbview.models import DbView
+    from dbview.models import DbView
 
-class ModelA(models.Model):
+    class ModelA(models.Model):
-    fielda = models.CharField()
+        fielda = models.CharField()
-    fieldc = models.IntegerField()
+        fieldc = models.IntegerField()
+
+    class MyView(DbView):
+        fieldA = models.OneToOneField(ModelA, primary_key=True,
+            db_column='fielda__id')
+        fieldB = models.IntegerField(blank=True, null=True, db_column='fieldb')
+
+        @classmethod
+        def view(klass):
+            '''
+            This method returns the SQL string that creates the view, in this
+            example fieldB is the result of annotating another column
+            '''
+            qs = modelA.objects.all().\
+                 annotate(fieldb=models.Sum('fieldc')) .\
+                 annotate(fielda__id=models.F('pk')) .\
+                 order_by('fielda__id') .\
+                 values('fielda__id', 'fieldb')
+            return str(qs.query)
+    ```
 
 
-class MyView(DbView):
-    fieldA = models.OneToOneField(ModelA, primary_key=True,
-                                  db_column='fielda__id')
-    fieldB = models.IntegerField(blank=True, null=True, db_column='fieldb')
-
-    @classmethod
-    def view(klass):
-        '''
-        This method returns the SQL string that creates the view, in this
-        example fieldB is the result of annotating another column
-        '''
-        qs = modelA.objects.all().\
-             annotate(fieldb=models.Sum('fieldc')) .\
-             annotate(fielda__id=models.F('pk')) .\
-             order_by('fielda__id') .\
-             values('fielda__id', 'fieldb')
-        return str(qs.query)

 3. Then create a migration point for your view generation, edit that migration
 and modify it, add: `from dbview.helpers import CreateView` and replace the line
 the call to `migrations.CreateModel` with `CreateView`.

 4. Migrate your database and start using your database views.
