Hi Gyan. I'm not a developer by any stretch of the imagination, but I've a 
pretty good command of the English language and experience in writing user 
documentation, as well as a rudimentary understanding of ffmpeg as it applies 
to stuff that I've needed to do with it. 

I'd be happy to assist with proof-reading/editing/style checks as appropriate 
(and I'm sure I'll learn lots along the way by doing so). 

For a long time I've been of the opinion that ffmpeg documentation has (to 
date) been written by developers, for developers, with lots of inherent 
assumptions about what the users of the documentation should know, instead of 
being written for users with little-to-no technical background or knowledge of 
the inner workings of ffmpeg and its associated libraries, filters etc, and 
that this would be addressed by a dedicated "documentation team" working with 
the developers (those who are willing) to produce and maintain user-level 
documentation to supplement the dev-level documentation. 

I think what you're proposing is a good step in that direction, and I'll be 
happy to help where I can.
