Friendly feedback, I think you'll attract more readers if you take the time to introduce the reader to the subject you're describing.

The article says it's a follow-up to a previous post but doesn't link to a previous post. Looking at the post index shows no other posts. That's alienating to readers who haven't read the previous post (which is most readers). You can make the article more accessible by catching the reader up to speed in a few sentences about what they need to know.

The article also never explains what telegra.ph is, and I suspect that 90% or more of HN has never heard of the website. Even if you visit the URL, it's unclear what the website does. Some sort of blogging platform?
