No docs or instructions

[EthraZa]

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.
