README someone can actually start from

[LukasNiessen]

Install, a first rule in ten lines, the fluent API grammar, one example per module, and a short note on what is not implemented yet.

Document from the source, never from a sibling's README — ArchUnitTS's documents a slice API that does not exist, and that is exactly the trap.

[TristanKruse]

README groundwork landed in 66708e6, 70ecf87, and 1e78888: current prototype status, source-checkout quickstart, direct graph API, extraction support/limitations, cache behavior, ignore directives, projection status, CI badges, and the live public RAG fixture are now documented. This stays open until the gem is published and a first fluent architecture rule can replace the source-checkout/direct-graph onboarding.
