+Overview
+--------
+
+Connecting to a MongoDB deployment requires the following components:
+
+- **Connection URI**, also known as a *connection string*, which tells the {+driver-short+}
+  which MongoDB deployment to connect to.
+- **MongoClient** object, which creates and sustains the connection to the MongoDB deployment
+  and lets you perform data operations.
+
+You can also specify connection settings in either of these components to customize the way
+the {+driver-short+} behaves while connected to MongoDB.
+
+This guide shows you how to create a connection URI and use a ``MongoClient`` object
+to connect to MongoDB.

+-----------

+To create a connection to MongoDB, pass a connection URI to the
+``MongoClient`` constructor. In the following example, the driver uses a sample
+connection URI to connect to a MongoDB deployment running on port ``27017`` of ``localhost``:
+
+.. code-block:: csharp

-   :end-before: // end local connection
+Configure the MongoClient
+-------------------------
 
-.. tip:: Reuse Your Client
+You can configure settings for the ``MongoClient`` object by passing a
+``MongoClientSettings`` object to the constructor. The following example creates a
+``MongoClient`` object and sets the ``UseTls`` property to ``true``:
 
-   Because each ``MongoClient`` represents a pool of connections to the
-   database, most applications require only a single instance of
-   ``MongoClient``, even across multiple requests. To learn more about
-   how connection pools work in the driver, see the :ref:`FAQ page
-   <csharp-faq-connection-pool>`.
+.. code-block:: csharp
 
-See :manual:`the MongoDB Manual </reference/connection-string>` for more information about creating a connection string.
+   var connectionString = "mongodb://localhost:27017/"
+   var settings = MongoClientSettings.FromConnectionString(connectionString);
+   settings.UseTls = true;
 
-MongoClientSettings
--------------------
+To view a full list of the settings you can configure, see the
+:ref:`csharp-connection-options` guide.
 
-You can use a ``MongoClientSettings`` object to configure the connection in code
-rather than in a connection URI. To use a ``MongoClientSettings`` object, create an 
-instance of the class and pass it as an argument to the ``MongoClient`` constructor.
