SLSA (pronounced ["salsa"](https://www.google.com/search?q=how+to+pronounce+salsa)) is a security framework from source to service, giving anyone working with software a common language for increasing levels of software security and supply chain integrity. It’s how you get from safe enough to being as resilient as possible, at any link in the chain.

## Learning about SLSA

See https://slsa.dev to learn about SLSA.

## What's in this repo?

The primary content of this repo is the [spec/](spec/) directory which contains
the core SLSA specification and the [www/](www/) directory which contains the
sources of the [slsa.dev] website. See the README.md in that directory for instructions
on how to build the site.

The `spec/` folder on the main branch contains the current Draft specification.
The released versions of the spec are found in the same folder but on the corresponding
release branch (i.e., `releases/v1.0`, `releases/v1.2`, etc.)

This repository also hosts SLSA's main [issue tracker], covering the website,
specification, and overall project management. Other git repositories within the
[slsa-framework](https://github.com/slsa-framework) organization have
repo-specific issue trackers.
