I wrote a detailed post[0] (also on dev.to) about how to write technical posts. Submitted it earlier today but didnt hit the front page. Hope you find it useful. Feel free to ask questions.
Intro
Many software developers blog to share technical knowledge and experiences. Some don't realize that sharing that technical knowledge is a skill they must develop on top of basic blogging skills.
This post explains how to structure a technical post, provides examples, and includes personal tips.
