+## ----- Tips on adding something to the new instructor dashboard -----
+## 1. add your input element, e.g. in instructor_dashboard2/data_download.html
+##   the input includes a reference like data-endpoint="${ section_data['get_anon_ids_url'] }"
+## 2. Go to the old dashboard djangoapps/instructor/views/instructor_dashboard.py and
+##   add in a definition of 'xxx_url' in the right section_data for whatever page your
+##   feature is on.
+## 3. Add a url() entry in api_urls.py
+## 4. Over in lms/static/coffee/src/instructor_dashboard/ there there are .coffee files
+##   for each page which define the .js. Edit this to make your input do something
+##   when clicked. The .coffee files use the name=xx to pick out inputs, not id=
+## 5. Implement your standard django/python in lms/djangoapps/instructor/views/api.py
+## 6. And tests go in lms/djangoapps/instructor/tests/
