-This repository is a template used by the noir-lang org when creating internally maintained libraries.

-This provides out of the box:
-
-- A simple CI setup to test and format the library
-- A canary flagging up compilation failures on nightly releases.
-- A [release-please](https://github.com/googleapis/release-please) setup to ease creating releases for the library.

-Feel free to use this template as a starting point to create your own Noir libraries.
