+### Applying a default scope
+
+If we wish for a scope to be applied across all queries to the model we can use the
+`default_scope` method within the model itself.
+
+```ruby
+class Client < ActiveRecord::Base
+  default_scope { where("removed_at IS NULL") }
+end
+```
+
+When queries are executed on this model, the SQL query will now look something like
+this:
+
+```sql
+SELECT * FROM clients WHERE removed_at IS NULL
+```
+
+If you need to do more complex things with a default scope, you can alternatively
+define it as a class method:
+
+```ruby
+class Client < ActiveRecord::Base
+  def self.default_scope
+    # Should return an ActiveRecord::Relation.
+  end
+end

 ### Removing All Scoping
 
 If we wish to remove scoping for any reason we can use the `unscoped` method. This is
