Still a WIP

I was also working on a simplified work flow diagram. WDYT?

I would also like to suggest to use the same logo used on Meilix repo.

@tabesin: This is a trivial web app that does not require much documentation other than the code or complex component descriptions.

I agree, but it took a group of(around 5 people, including me) more than an hour to understand and setup the whole thing with help from @meets2tarun and @xeon-zolt.

It was just quite complex to find where everything was and why it wasn't working. My main goal for this PR was to improve docs on Travis setup, which where other new people in the group struggled on(i've had previous Travis experiance).
