what is the best workflow to write documntation ?

[quote author="Colin Williams" date="1262494453"]I typically sketch out my code as sort of an abstract class, and maybe map out the API/workflow in pencil and paper if its complexity necessitates it. Then I take that and start writing the documentation--yes, before completing the code. The documentation basically becomes a road map for development. They grow and change side by side. Sometime what you planned has to change for technical reasons, and other times it becomes unnecessarily difficult to explain the API, so you change the API to make it more simple.[/quote]
thanks colin,
i can see your way in writing the docs , but the problem is ... i take alot of time writing the same page title over and over in the page ... a lot of time to format the page ,, any programs would facilitate the way i can write the docs ?
