Implementation Made Easier for Non-Engineers

**Motivation**
Buzz is attracting interest from people in customer success, sales, operations, and other non-technical roles. The current setup documentation assumes familiarity with concepts like workspaces, relays, self-hosting, and building from source, which can make it difficult to know where to start.

**Proposed solution**
Add a short beginner-friendly setup guide that:

* Explains Buzz in plain language
* Helps users choose the right installation path
* Defines terms like workspace, relay, and self-hosting
* Includes screenshots for the main setup steps

**Alternatives considered**
Community guides and videos can help, but official documentation is easier to trust and keep current.

**Additional context**
I’ve seen several non-technical users express interest in Buzz but feel overwhelmed getting started. I ran into the same experience and ended up creating my own install guide. The attached screenshot shows the current onboarding page that prompted this suggestion.

Closest existing issue: None found.


Start by reviewing the current setup documentation and the onboarding page shown in the attached screenshot, then map the available installation paths and terms such as workspace, relay, and self-hosting. Done means a short official guide explains Buzz plainly, helps users choose an installation path, defines those terms, and includes screenshots for the main setup steps.
