  1. Hi Eric,
    Thank you for creating this tutorial. I am trying to follow along but I get lost almost right away. I have Prepros but where can I find the folders (lesstuts) that you are using to compile the less to css?

  2. Eric Young says:


    You can drag any folder and make it your project folder, In the video I used less tuts as my project folder which was the folder that I used to make these tutorials. Let me know if you have any more questions.
