Labor specialization helped spur the Industrial Revolution and the technology-driven world in which we live. I firmly believe that startups are the equivalent of this century, providing the the building blocks for today's apps:

  • Sendgrid spent years thinking about e-mail delivery.
  • Stripe has been processing payments for 4 years.
  • Twilio has cracked all the details of guarranted SMS delivery across the world.
  • Auth0 has experts on the subject that went through every detail of authentication, authorization and user management.
  • ... and so on

Which style would you prefer for a blog post?

Why developers fall in love with your product?

1. Awesome docs

What do we do the first time we want to use a library? We read the Github README or the Wiki. Why? First and foremost, because we can do what we know best: Copy & Paste code snippets. Also, it gives us an overview of how we can use the library and the APIs it has. If the APIs weren’t good, we’d just search for another one.

Products should follow this same idea. We should have documentation from which we can copy and paste. For a product, that means tailored documentation for every user.

Another thing we love is reading code. It’s literature for us!That’s why it’s nice if every document includes an up-to-date sample for every major platform/technology that we can just download, run locally and read its code.
