Ask HN: Can you share your process on how you write articles/tutorials?

I began blogging 2 months ago but I have a hard time writing programming tutorials. It takes me a couple of days just to finish writing a single article.

My hardest part is research and the actual writing. Do you research first and then write an article? Or do you research while you are writing the article? What do you look for when researching?

I would really appreciate if you would share your blogging workflow. Especially on how you research and write an article.
