This morning I downloaded and installed an open source module. I ran it and it showed a form with several inputs. I couldn't deduce what one field is used for or in what format. It kept erroring. I checked the module zip file for any documentation. Nothing. The site had nothing. Just one install module and one source module. 

While some piece of software might be free and I should be happy, it still bugs me that I have to spend an inordinate amount of time figuring it out and conclude it's not something which will work for me. If a developer takes hours or days to develop some software, take 5-10 minutes and jot down some quick getting started info or some explanation for the input fields. We don't expect any fancy documentation.  A text file with spelling and grammar mistakes is better than nothing. Don't worry about styles. It amuses me when a developer takes time to include a long detailed ReleaseNotes text file with mention of every minor version and bug fix but doesn't have any kind of documentation. To a user which file is more important!? When I download some software I have zero interest what the prior versions did and what got fixed. I want software that is the latest version, that works now and I want to understand it quickly.

So please be considerate and include some quick docs. Our time is also valuable. Don't waste the time of tens or hundreds of users because you were too lazy to write something down. Put yourself in the shoes of a user who knows nothing of your software and pretend you're using it for the first time and then write some docs and examples for areas that thser user mightbe lost. Or at least give it to a friend and ask them which areas they had difficulty with and make that easier either in the UI or in some documentation.

It's not Form and List and I won't mention which one :) Now every module which doesn't have any kind of documentation is a suspect.
