I am not sure this is the right place to post this question; could not find any better…
Is there an overview of what HA consists of? I see many names in the forum and docs, like HA, HA Core, HA OS, Hass.io, supervisor and so on. It’s really hard to get oriented.
The rest is explained in the Getting Started section of the documentation, including the installation methods, which relate to naming and the components, which are defined by integrations.
