Trying to add HACS to HA Green

Third party integrations
1

Hi,
I’m new to HA so I bought a HA Green.

I’ve powered it up, downloaded the IOS app, connected to the system and discovered (?) a load of my home devices (Hive, Sonos, etc).

Now I want to add the HACS but can’t see how to.
I’ve googled and the option it shows, Settings-Add ons, isn’t there.

How do I move forward?

TIA for any help!

Many thanks, Nathan.
Got it now. It was just a case of finding those instructions for the first steps.

I’m sure there will be more basic questions to follow!
