quickstart

Currently just clone the project and just start the cli (that will create a virtualenv and installs every dependencies)

e.g.:

~$ git clone https://github.com/jedie/inverter-connect.git
~$ cd inverter-connect
~/inverter-connect$ ./cli.py --help

The output of ./cli.py --help looks like:

Usage: ./cli.py [OPTIONS] COMMAND [ARGS]...
