+CRUD (Create, Read, Update, Delete) operations allow you to work with
+the data stored in MongoDB.
+
+The CRUD operation documentation is categorized in two sections:
+
+..
+  - :doc:`Read Operations </fundamentals/crud/read>` find and return
+    documents stored within your MongoDB database.
+  - :doc:`Write Operations </fundamentals/crud/write>` insert, modify,
+    or delete documents in your MongoDB database.
+
+..
+  Some operations combine aspects of read and write operations. See our
+  guide on :doc:`compound operations </fundamentals/crud/compound-operations>`
+  to learn more about these hybrid methods.
