+Use
+---
+
+You can use these stores like this:
+
+.. code-block:: python
+
+    from rdflib import Graph
+    
+    # use the default memory Store
+    graph = Graph()
+    
+    # use the BerkeleyDB Store
+    graph = Graph(store="BerkeleyDB")
+
+
+In some cases, you must explicitly _open_ and _close_ a store, for example:
+
+.. code-block:: python
+
+    from rdflib import Graph
+    
+    # use the BerkeleyDB Store
+    graph = Graph(store="BerkeleyDB")
+    graph.open("/some/folder/location")
+    # do things ...
+    graph.close()
+
