 SLSA now provides and maintains official builders for [Go](2022/06/slsa-github-workflows), [Node.js](2023/05/bringing-improved-supply-chain-security-to-the-nodejs-ecosystem) and [Container](2023/06/slsa-github-worfklows-container-based) based projects.
 But what if you don't use any of these languages or use custom tooling that isn't supported by the official builders?
 
-To empower the community to create their own provenance builders and leverage the secure architecture of the official SLSA builders we are releasing the ["Build Your Own Builder" framework](https://github.com/slsa-framework/slsa-github-generator/tree/main#build-your-own-builder) for GitHub Actions. This makes it easy to take an existing GitHub Action (e.g. [JReleaser](https://jreleaser.org/)) and make it produce [SLSA Build Level 3 provenance](https://slsa.dev/spec/v1.0/requirements#provenance-generation).

 Writing a builder from scratch is a tedious multi-month effort. The BYOB framework streamlines this process and cuts the development time down to a few days. As a builder author, you don't need to worry about keeping signing keys secure, isolation between builds, the creation of attestations; all this is handled seamlessly by the framework, using the [same security design principles](https://github.com/slsa-framework/slsa-github-generator/tree/main#specifications) as our existing builders.

 The BYOB framework benefits both GitHub Action maintainers and GitHub Action users:

 2.  For Action users, it makes it easy to adopt SLSA by trusting the BYOB project and the Action code - without worrying about which machine runs the Action.
 
 The BYOB framework provides a set of GitHub Actions and workflows that helps builder authors generate provenance.
