Acknowledgements

Sätteri builds on the work and knowledge of several open-source projects:

• unifiedjs -- the ecosystem of tools for processing content with syntax trees, including remark and rehype
• pulldown-cmark -- CommonMark pull parser
• mdxjs-rs -- MDX compiler by Titus Wormer, forked to use pulldown-cmark and OXC

Special thanks to the following projects for paving the way for high-performance Rust <-> JavaScript interop:

• oxc -- Rust JavaScript parser and compiler by the OXC team, used for MDX compilation
• Lightning CSS -- Rust CSS parser with a optimized JavaScript Visitor API

Sätteri is an open-source project born from Bruits, a Rust-focused collective 💛
