Ask HN: How do you create help docs/videos?

I'd love to get some advice from my fellow hackers about this.

I love coding, but I hate writing the help files and god forbid shooting the help videos. And I'm sure I'm not alone.

Is there any trick, technique or system that you use to get those all-important help files created for your webapp?

Is there a service somewhere that can do it for you? Or help you in some way?

My current project is especially plagued by my lack of detailed, step-by-step help files. It's trying to get people with no tech savvy (doctors, lawyers, real estate agents) to do something that requires at least some tech knowledge: setting up a simple website. People really need to have their hands held and shown exactly what to do, and I'm having trouble providing that for them.

Any advice would be highly appreciated.
