I am new to HA. I have been unsuccessful in installing HACS on Home Assistant Green. I am able to install the GET HACS app from Github, I reboot HA, but when I go to Add Integration in Devices and Services and search for HACS it does not show up.
You’ve followed this guide? Downloading HACS - HACS
and then as part of step1 this: Common tasks - Home Assistant Operating System - Home Assistant which shows how to setup repositories for things like cards and some devices and services to run on HA
