Why it exists
A small installer wizard from the era when deploying a PHP app meant hand-editing config files and running SQL by hand. It walked the user through database credentials, created the schema, and checked for an existing installation before touching anything.
What I learned
An early lesson in making setup safe to re-run: idempotency and a clear pre-flight check before any writes. The kind of thinking that gets boring in the abstract and very valuable in production.
Status
Archived. Replaced in practice by migration frameworks, container images, and infrastructure-as-code — but the underlying habit (check before you write) has stuck around.
