1. Trying to understand what the subject is about by searching information in google and youtube, like "What is _subject_?" and looking in wikipedia page. 2. Looking in google, youtube, wikipedia for alternatives. 3. Reading introduction section in official documentation. 4. If on previous steps I decided that I need to learn new subject I am starting looking and buying book at Amazon or Udemy course (prioritizing books over Udemy courses). 5. Staring reading book or doing Udemy course and in parallel reading official documentation.
