Not sure where to post this

For the past few months I have been teaching myself MQTT, Node Red and Fauxmo, and learning to program the esp8266 modules in Arduino IDE. I kept seeing references to Home Assistant, so I figured I should look into it. But where? I first went to Wikipedia only to see the Home Assistant page tagged for deletion. So, here I am. Interested in learning about Home Assistant, but nowhere to go to learn about the features of HA and how it might fit into my Smart Home plans.

so, does anyone want to point me in the right ‘getting started’ direction?

Have a read through the main pages, then check out some peoples examples here:
Floorplans

Alarm system

There is plenty to learn but definitely start with the main website
