+
+Overview
+--------
+
+In this guide, you can learn how to use the {+driver-long+} to perform
+**aggregation operations**.
+
+Aggregation operations process data in your MongoDB collections and
+return computed results. The MongoDB Aggregation framework is modeled on the 
+concept of data processing pipelines. Documents enter a pipeline comprised of one or
+more stages, and this pipeline transforms the documents into an aggregated result.
+
+To learn more about the aggregation stages supported by the {+driver-short+}, see
+:ref:`Aggregation Stages <csharp-aggregation-stages>`.

+
+Analogy
+~~~~~~~
+
+Aggregation operations function similarly to car factories with assembly
+lines. The assembly lines have stations with specialized tools to
+perform specific tasks. For example, when building a car, the assembly
+line begins with the frame. Then, as the car frame moves through the
+assembly line, each station assembles a separate part. The result is a
+transformed final product, the finished car.
+
+The assembly line represents the *aggregation pipeline*, the individual
+stations represent the *aggregation stages*, the specialized tools
+represent the *expression operators*, and the finished product
+represents the *aggregated result*.
+
+Compare Aggregation and Find Operations
+---------------------------------------
+
+The following table lists the different tasks you can perform with find
+operations, compared to what you can achieve with aggregation
+operations. The aggregation framework provides expanded functionality
+that allows you to transform and manipulate your data.

+       | Connect and merge data sets
+
+Server Limitations
+------------------
+
+Consider the following :manual:`limitations </core/aggregation-pipeline-limits/>` when 
+performing aggregation operations:
+
+- Returned documents must not violate the :manual:`BSON document size limit </reference/limits/#mongodb-limit-BSON-Document-Size>`
+  of 16 megabytes.
+
+- Pipeline stages have a memory limit of 100 megabytes by default. If required, you can exceed this limit by setting
+  the `AllowDiskUse <{+new-api-root+}/MongoDB.Driver/MongoDB.Driver.AggregateOptions.AllowDiskUse.html#MongoDB_Driver_AggregateOptions_AllowDiskUse>`__
+  property of the ``AggregateOptions`` object that you pass to the ``Aggregate()`` method.
