# This workflow uses actions that are not certified by GitHub.
|

|
|
# They are provided by a third-party and are governed by
|

# separate terms of service, privacy policy, and support

# This workflow lets you generate SLSA provenance file for your project.
|
||
|
|
# The generation satisfies level 3 for the provenance requirements - see https://slsa.dev/spec/v0.1/requirements
|
||
|
|
# The project is an initiative of the OpenSSF (openssf.org) and is developed at
|
||
|
|
# https://github.com/slsa-framework/slsa-github-generator.
|
||
|
|
# 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.
