The most important step to launching effective docs
Your first step should be to ask what "good" looks like. What's your objective for publishing this article / help center / explainer video / developer documentation / etc ? What results would you ideally like to see?
Once you're clear on your desired outcome, you'll have a good idea of exactly what needs to be in the article. And once you know that, your article might practically write itself. (More on this in a minute...)
For a new product, "good" usually = adoption. The user documentation must answer the questions new users will have. It must remove, or significantly reduce the friction to adoption.
For a mature product with strong adoption, "good" = serviceability. The user documentation must reduce the number of support requests.
Now that you're clear on what your article needs to accomplish, how might it "practically write itself"?
Your PRD already has most of the information/use cases/examples/etc that users need to successfully adopt your product. It just needs to be presented in a user friendly format that includes only the information relevant to users.
Paste your PRD into ChatGPT / Gemini / etc and ask it to draft your article. ChatGPT does a pretty good job of this. Even better, paste your PRD into Docs-writer.ai, which I created specifically for this purpose. Docs-writer.ai is free, you'll get better results, and you won't spend time refining prompts to get what you want.
To wrap up: Get clear on your objective. Don't skip this step. Your users will thank you and you'll improve product outcomes.
