+    Murano agent development uses virtualenv to track and manage Python dependencies
+    while in development and testing.
+
+    To activate the Murano agent virtualenv for the extent of your current shell
+    session you can run:
+
+    $ source %s/bin/activate
+
+    Or, if you prefer, you can run commands in the virtualenv on a case by case
+    basis by running:
+
+    $ %s/tools/with_venv.sh <your command>
+
+    Also, make test will automatically use the virtualenv.
