# in-toto Attestation Framework The in-toto Attestation Framework provides a specification for generating verifiable claims about any aspect of how a piece of software is produced. Consumers or users of software can then validate the origins of the software, and establish trust in its supply chain, using in-toto attestations. ## Learning about in-toto attestations To get started, check out the [overview] of the in-toto Attestation Framework. For a deeper dive, we recommend reading through our [documentation] to learn more about the goals of the in-toto Attestation Framework. If you encountered in-toto via the SLSA project, take a look at this [blog post](https://slsa.dev/blog/2023/05/in-toto-and-slsa) to understand how the two frameworks intersect and how you can use in-toto for SLSA. Visit [https://in-toto.io](https://in-toto.io) to learn about the larger in-toto project. ## Working with in-toto attestations The core of the in-toto Attestation Framework is the [specification] that defines the format for in-toto attestations and the metadata they contain. We also provide a set of [attestation predicates], which are metadata formats vetted by our maintainers to cover a number of common use cases. For tooling integration, we provide [protobuf definitions] of the spec. We currently provide language bindings for Go, Python, Rust and Java, with Go being the most mature, and Rust being the most recent addition. ## Is your use case not covered by existing predicate types? Take a look at the open [issues] or [pull requests] to see if your usage has already been reported. We can help with use cases, thinking through options, and questions about existing predicates. Feel free to comment on an existing issue or PR. ## Want to propose a new predicate type? If you still can't find what you're looking for, open a new issue or pull request. Before opening a request for a new metadata format, please review our [New Predicate Guidelines]. ## Governance The in-toto Attestation Framework is part of the [in-toto] project under the [CNCF]. For more information, see [GOVERNANCE.md]. Use `@in-toto/attestation-maintainers` to tag the maintainers on GitHub. ## Insights and Activities Stay up-to-date with the latest activities and join discussions about the in-toto Attestation Framework through our Slack channel [#in-toto-attestations](https://cloud-native.slack.com/archives/C06HBJUEJBT). ## Disclaimer The in-toto Attestation Framework is still under development. We are in the process of developing tooling to enable better integration and adoption of the framework. In the meantime, please visit any of the language-specific [in-toto implementations] to become familiar with current tooling options.
