First and foremost here is my example of sourcetree.
I’d just like to say that I really like this tool. I have been learning Unity and C# for the past few months and I have already learned a lot of skills. Nonetheless I have been doing this course from scratch as if I was a total beginner. I found that, in all the basic tutorials that I watch there is always something new to learn and it is very important to reinforce our knowledge of the basics.
So for people that (as I read in some reviews) think that this is too basic or too beginner friendly, believe me there is always something new to learn that might have escaped you in other classes/tutorials.
Cheers and happy learning!
