@JayGray & @mschaaf,

We could start this. I would be happy to get this started. We'll just have to decide what kind of file format we'd like to have it in?

@willbenica
You can use the project wiki page. Should be easy to add, edit pages. I think a good starting point to how write wiki pages in github could be:
http://markdown.de/syntax/
Unfortunately in German. ;)

[mschaaf]

And this markdown can be used in the project readme.md and then github can generate from this file a nice and simple web site too.

Added a few basic pages to the wiki.
Not much that I could do right now.

[mschaaf]

We need a description of our application in the following places: README.md, package.json, wiki and dist specific files e.g. mac plist file.

[mschaaf]

We should have in our wiki descriptions about the features:

• pressing return to send and also to use the send button for sending
• drag and drop files in the message to send text box leads to sending the file
• message list shows the last 10 messages
• explain the client list

[mschaaf]

We should prepare description about using our dist packages.

[JayGray]

We should also add our used node-modules like adm-zip and polo.

I added this wiki page https://github.com/Dica-Developer/quickQuestion/wiki/User-Documentation with lots of bullet point descriptions. What it now needs is some sentence made out of it.
