Update Readme for installation?

[metawops]

Hi @MickMake,

my SunGrow infrastructure here at home is being installed as I type ... and while it's not yet working and producing energy I already checked how/if I could integrate the data from the iSolarCloud portal (I'm using the EU version) into my Home Assistant installation.
A quick search brought your repository up – AWESOME work!! 🤩🎉🙌

However, the readme.md file seems to be a bit outdated. There is no supervisor menu/mode any more in HA (at least I can't find it here on my local installation) and I was wondering if this could be installed via HACS? Or, if not, how it could be installed at all. Maybe others are wondering, too? Or maybe I'm just too dumb. 🙈

Anyway, I was thinking a little update of the readme file would be awesome ...?!
Thanks SO much for your work!!

Cheers,
Stefan.

UPDATE:
Oh, I found it. It's now Settings > Add-ons > ADD-ON STORE and then the three dots! ✅
