Hi @aizfren!

Since this is your first contribution to utopian-io, I suggest that you acquaint yourself to the Utopian Guidelines. And it is always important to have an active GitHub account, as part of Utopian's GitHub Integration Policy. After that, you may have a look to the templates per category as per tutorials category, here is the template. Additionally, based on your tutorial content, perhaps, the GitHub repository might be https://github.com/nodejs/node. Furthermore, it is highly appreciated that there are some explanations to the codes. Lastly, I recommend you taking a look of Utopian's Weekly Top Contributions across all categories - for the latest post, see Weekly Top of Utopian.
