Published API-only ruby on rails course, we’re building an Instapaper clone from scratch.

Hey indiehackers,

I started to publish API-only ruby on rails course on duetcode.io. We're implementing a functional clone of Instapaper.

It's a free, written course, and the course targets developers already familiar with ruby on rails tech stack. It's an ongoing course, I'm planning to publish a new chapter weekly.

Let me know if you have any feedback about the content or the website in general.
