The very first line of those errors is an error that you have to fix first.
It tells you that the syntax of your #include directive is not right.
Thus, I don't think you actually followed the instructions perfectly, because code that properly compiles cannot have that problem.
As a secondary concern, it would probably be useful for you to learn more about programming in general, so that you can diagnose these problems (or avoid them in the first place) yourself.
There are many good beginner Arduino tutorials, for example of a place where to get started.
