 ## [UDS Core Overview](https://uds.defenseunicorns.com/reference/uds-core/overview/)
 
 UDS Core establishes a secure baseline for cloud-native systems and ships with compliance documentation and first-class support for airgap/egress-limited systems. Based on the work of [Platform One](https://p1.dso.mil), UDS Core expands on the security posture of [Big Bang](https://repo1.dso.mil/big-bang/bigbang) while providing advanced automation with the [UDS Operator](./src/pepr/operator/README.md) and [UDS Policy Engine](./src/pepr/policies/README.md). UDS Core is a collection of several individual applications combined into a single [Zarf](https://zarf.dev) package and we recommend using [UDS CLI](https://github.com/defenseunicorns/uds-cli?tab=readme-ov-file#install) to deploy it as a [UDS Bundle](#using-uds-core-in-production).
