Add link to Integration documentation

[andriej]

The request

It would be very good to have Integration's documentation link while adding/configuring it, just as like it is with HA addons - there's always link at top and it makes finding proper docs very easy.

The alternatives

n/a

Additional information

It would be good to have it at least while configuring new Integration.

That reminds me, I did a rough mockup for this a year ago (also logos).

I agree this would be a good idea since there can often be some useful information / links in the docs about how to register for developer accounts and obtain API keys and whatnot.

However the one thing that gives me a little pause though, is that at present time the docs are very YAML oriented. If someone is adding it through the UI, then clicks a docs link for help and there's all this stuff about YAML, they could be confused and second guessing themselves? That will be less of a problem over time, just one potential drawback to consider right now.

Yes, I agree - it would need different approach to docs also... but maybe it's worth a try?
