-    helper method to set the virtual environment for the following commands
+    Context manager for setting the virtual environment for commands.
 
-    uses python yield command
+    This helper method sets up the virtual environment specified in the
+    configuration before executing any commands within its context. It uses
+    the Python context manager pattern with the `yield` keyword to
+    temporarily modify the environment for the duration of the with-block.
+    The virtual environment is specified by the name in
+    `configuration.virtualenv.name` and is activated using the `workon`
+    command.
+
+    Note:
+        - This method relies on the Fabric library's `prefix` context manager
+          and assumes the use of virtualenvwrapper or a similar tool for
+          managing virtual environments.
+        - The method expects `configuration.virtualenv.name` to be properly
+          set in `env.config`.
+
+    Example Usage:
+        with virtualenv():
+            run("python manage.py migrate")
