+# Sim Enterprise Edition
+
+This directory contains enterprise features that require a Sim Enterprise subscription
+for production use.
+
+## Features
+
+- **SSO (Single Sign-On)**: OIDC and SAML authentication integration
+- **Access Control**: Permission groups for fine-grained user access management
+- **Credential Sets**: Shared credential pools for email polling workflows
+
+## Licensing
+
+See [LICENSE](./LICENSE) for terms. Development and testing use is permitted.
+Production deployment requires an active Enterprise subscription.
+
+## Architecture
+
+Enterprise features are imported directly throughout the codebase. The `ee/` directory
+is required at build time. Feature visibility is controlled at runtime via environment
+variables (e.g., `NEXT_PUBLIC_ACCESS_CONTROL_ENABLED`, `NEXT_PUBLIC_SSO_ENABLED`).
