Hey thank you for your contribution, your blog seems fine, I'll ask you only one thing: Keep in mind that the slug, title, and description are essential parts of that blog's SEO, and therefore need to be as catchy as possible. Rewrite them so they can be indexed better. Literally 3/4 of visitors come just for blogs, lol.

Anyway thank you the other changes are good
