# @elastic/ecs

Automatically generated TypeScript type definitions for the
[Elastic Common Schema](https://www.elastic.co/guide/en/ecs/current/index.html).

When run, this program will fetch the ECS schema from the `elastic/ecs` repository. Defaults to `main` ref,
can be overridden with `--ref` flag.
