Suggestions for further refinements of this tutorial:

What format was the original data in? Do you have general tips for users for getting and importing this kind of data?

remember, the coordinates could be in other systems - in your project you used UTM (MTM?), so northings and eastings are appropriate, but there are other possibilities - could make instructions more general

When you generate slope maps, they can be in degrees or percent slope. Point this out to the user?

would be useful to explain a bit more what you are trying to do here (what the index is used for), and why there is a 2.718282 in the formula (natural logarithm)
