| # This workflow compiles frizbee using a SLSA3 compliant | |
| # build and then verifies the provenance of the built artifacts. | |
| # It releases the following architectures: amd64, arm64, and armv7 on Linux, | |
| # Windows, and macOS. | |
| # The provenance file can be verified using https://github.com/slsa-framework/slsa-verifier. | |
| # For more information about SLSA and how it improves the supply-chain, visit slsa.dev. | |
