No docs or instructions

I would like to suggest a couple of adds to the Readme file:

1- Simple installation instructions, like git clone and setup it here and there. Do we need to disable or enable core time tracking?
1- Is it compatible with the core time tracking? Like, will it mess up with it or use its data at all? If no, can I import its data?
2- How it compares to core time tracking?
3- One or two screenshots would be very cool too.

If you refer to "master" branch, this is an old implementation, nearly unmaintained
if you refer to development "next" branch, this is a work in progress, so all your points are acknowledged and should be added at some point
