+# Python
+
+The `python.submit` file submits one job that calls `analyze_subject.py` ---
+which simply prints out the subject ID that is passed to it.
+
+## Prerequisites
+This example assumes that it is located in `~/htcondor-templates/python`. If you
+have cloned it elsewhere, adjust the submit file as necessary.
+
+Otherwise, this example is entirely self contained.
