The complete script (in all its levels) is very comprehensive and you will certainly be more interested in some aspects of it than in other ones. With this possibility in mind, the tutorial has been designed so that you can go through it on a relatively short time, by simply reading the text and copying and pasting the embedded scripting code. And then, obviously, at any time, you can take a closer look at the parts of the source code of your interest to gain a deeper insight into the topics you prefer. Some hints in this direction have been given by adding the 
icon to some parts, indicating that you may be interested in taking a closer look at how that part has been implemented. Anyway, you can also walk through the entire tutorial neglecting these indications.Also, different workflows have been offered (for example, with more or less detail in how to build a SOBEK 3 flow model step by step). You can choose the path (and pace) that best fits your interests. Due to the different workflows available to follow this tutorial, some figures might not exactly match the situation of your model at the time reading them. This is not relevant at all. You should focus solely on the items of interest for the particular step in the script you are studying at that time.
