+## Build Environment track
+
+The goal of a Build Environment track is to enable the detection of tampering
+with core components of the compute environment executing builds.
+
+The current [draft version](../draft/attested-build-env-levels.md)
+of the Build Environment track includes the following requirements:
+
+- Generation and verification of SLSA Build Provenance for build images.
+- Validation of initial build environment system state against known good
+ reference values.
+- Deployment of the hosted build platform on a compute system that supports
+ system state measurement and attestation capabilities at the hardware level.
+
+These requirements are **subject to significant change** while this track
+is in draft.
