Fastmash welcomes contributions: bug reports, compatibility findings,
benchmarks from real workloads, documentation fixes and code.

- [Architecture](architecture.md): crates, the path of a command, sorting,
  numbers, errors and safety
- [Testing](testing.md): the test layers and how to run them
- [Glossary](glossary.md): the project's vocabulary
- [Decision records](../adr/index.md): the decisions that shape the design
