 Welcome to the documentation site for the official {+provider-long+}.
-You can add the provider to your .NET application as an object-relational mapper (ORM)
-to work with data in MongoDB.
+
+You can add the {+provider-short+} to your {+language-dotnet+} application as an
+object-relational mapper (ORM) to work with data in MongoDB. You can use the
+provider to access and manipulate data from your application without explicitly
+running database commands. The {+provider-short+} tracks any queries or data
+changes you make, and automatically runs them on the database by using the
+MongoDB Query API.
+
+Use the {+provider-long+} if you want to build a {+language-dotnet+} application
+that uses {+framework-core+} with MongoDB.

 Download the provider by using `NuGet <https://www.nuget.org/packages/{+package+}>`__,
