+This script takes tab delimited input file like so and automatically
+creates the folder structure along with empty README files, per the contributing
+guidelines. If you copy-paste from Google sheets, it will automatically add
+tabs.
+
+* Copy-paste the file below into `outline.txt` (too lazy to parameterize this
+script) in the directory of the module that you want to use, i.e.,
+`module5-testing/outline.txt`
+* cd to the correct directory (this step is important for the working directory
+to be correct)
+* Run `python ../make_structure.py`
+* Enjoy your created structure
