This handbook will get you on the way to be a great developer advocate for any product or company. Naturally, your approach may need tweaking for different markets and audiences - and in accordance with your own personality - but the main principles are the same for everybody and anywhere in the world.
This is a new, 2020 version of this 11 year old book and I added quite a few new chapters and removed outdated materials. You can read more about this in the about section.
Now, why not get right into it? Choose from the table of contents or read the book.
