# Notes

> ORY Keto is still a `sandbox` project and the included APIs are unstable until
> we reach `v1` and release `v1.0.0` of Keto!
>
> Older API versions, such as `v1alpha2`, will still get support for a
> reasonable amount of time after release of `v1`!

This directory contains the ProtoBuf & gRPC definitions for the Access Control
APIs.

**ACL is the flexible and scalable "base system" all other access control
schemes built upon.**
