-## Editing the specification
-
-Edits to the specification are done in the `spec.bs` file, which is then compiled with the [Bikeshed](https://tabatkins.github.io/bikeshed/) spec pre-processor.
-
-To build the specification, you can use one of:
-
-- `make local`: uses a locally-installed copy of Bikeshed
-- `make remote`: uses a Bikeshed web service, so you don't have to install anything locally
