ClickHouse/docs/get-started

# Get started

**What goes here:** Onboarding material for new users. Quickstarts, install /
setup instructions, sample datasets, "about" pages, and use-case landing pages
that route a new user to the right starting point.

**Audience:** Someone evaluating ClickHouse or running it for the first time.
Pages here should get a reader to a working install or first query as quickly
as possible.

**Subdirectories:**
- `about/` — what ClickHouse is, why it's fast, comparisons.
- `quickstarts/` — minimal "do this in 5 minutes" walkthroughs.
- `setup/` — install + connect, including Cloud and migration guides.
- `sample-datasets/` — datasets to query against while learning.
- `use-cases/` — landing pages routing users by goal (analytics, observability, ML).
- `oss/` — content specific to running ClickHouse OSS yourself.

If a page assumes the reader already has ClickHouse running, it does not
belong here — put it in `/guides` or `/concepts`.
