UPDATE README. Make it easier for Novice Users

[MankiniChykan]

I tried this node a few years back and only just got it going today. I will admit I have gained a fair bit more experience now than I had two years ago but your instructions are not clear for a novice.

If you could update your README on Node Red and Git Hub that would make it much clearer on how to setup this node for the novice.

Possibly adding a picture of the nodes required.

EXAMPLE: (From your comment in your example - it was not until I downloaded this example flow I got it working)

**You will need to configure a tado_config node with your Tado Username and Password before using the examples

You should also replace the home_id in the calls with your home_id which can be found using the first example of getMe API call.

You can read your 'home_id' in the debug window.**
