-Sample Class
-------------
-
-The code examples in this guide demonstrate how you can use builders to
-create types to interact with documents in the sample collection ``plants.flowers``.
-Documents in this collection are modeled by the following ``Flower`` class:
-
-.. literalinclude:: /includes/fundamentals/code-examples/builders.cs
-   :language: csharp
-   :dedent:
-   :start-after: start-model
-   :end-before: end-model
-
-Each builder class takes a generic type parameter
-``TDocument`` which represents the type of document that you are working
-with. In this guide, the ``Flower`` class is the document type used in
-each builder class example.
-
-Define an Update
-----------------
-
-The ``UpdateDefinitionBuilder`` class provides a type-safe interface for
-building up an update specification. Suppose you want to create an
-update specification with the following criteria:
-
-- Create the new field ``SunRequirement``
-- Multiply the ``Price`` field value by 0.9
-
-Use builders to create the update specification with the typed variant:
-
-.. code-block:: csharp
-   :copyable: true
-
-   var builder = Builders<Flower>.Update;
-   var update = builder.Set(f => f.SunRequirement, "Full sun").Mul(f => f.Price, 0.9);
-
-Alternatively, you can use string-based field names to define the update:
-   
-.. code-block:: csharp
-   :copyable: true
-
-   var builder = Builders<Flower>.Update;
-   var update = builder.Set("SunRequirement", "Full sun").Mul("Price", 0.9);
