Configuring Hive

Just started using Home Assistant a couple of days ago, so apologies for stupid question.
I’m getting weather data from the Met Office integration, and will be a while before I get my temperature and humidity sensors so thought I’d try the Hive integration, and monitor what the thernostat is doing.
I found and have edited the configuration.yaml file as instructed. But what else do I need to do? The page implies that that’s all I have to do, but surely there is some software to install?

I was able to add via Configuration > Integrations > +Add Integration. However the Hive integration seems to have disappeared :worried: It is the same on both my HA Server and test virtual machine…

That’s a shame. I thought the recent Hive upgrade issue had been sorted, and it was good to use once again:(
