# MCAP
MCAP is a logging library and file format. It is commonly used in robotics applications, and works well under various workloads, resource constraints, and durability requirements.
## Documentation
- [File format specification](https://mcap.dev/spec)
- [Kaitai Struct definition](./website/docs/spec/mcap.ksy)
- [Motivation](https://mcap.dev/files/evaluation.pdf)
- [Support Matrix](https://mcap.dev/reference)
## Quickstart
MCAP libraries are provided in the following languages. For guidance on each language, see its corresponding README:
| Language | Readme | API docs | Package name | Version |
