+# Python prep guidelines
+
+On lecture 1, I informed you that you will be writing Python code as part of
+the 3 cases you will need to go through in this course. This means that, the
+more you know about Python, the less you will need to focus on *how* to do
+things with Python and the *more* you will be able to focus on actually solving
+the case.
+
+This preparation is specially important if you have never done any coding. I
+highly advise you to take your time to work your Python skills out before case
+1 begins. It will pay off down the line.
+
+This document contains two sections: a summary of the skills you are looking
+for, and a few suggested contents that can help you. You don't need to use
+suggested contents: if you find others that you prefer, go ahead. I do
+recommend that you stick to trying to learn the skills I am suggesting, since
+that will maximize the return on your effort. There are many other areas of
+Python that you can learn but won't be relevant for this course.
