 ## Spec and API development
 
-For the nitty-gritty of the API, the draft W3C specifications are authoritative. [Service Workers Nightly](https://w3c.github.io/ServiceWorker/) is a living document. [Service Workers 1](https://w3c.github.io/ServiceWorker/v1/) is a version that is advancing toward a W3C Recommendation. For implementers and developers who seek all the latest features, [Service Workers Nightly](https://w3c.github.io/ServiceWorker/) is a right document that is constantly reflecting new requirements. For version 1, contributors plan to focus on fixing bugs and resolving compatibility issues without including new features from the nightly version.
