+# Tenant Package
+
+Multi-tenancy, user management, and entitlement systems for the Host UK platform.
+
+## Overview
+
+The `core-tenant` package is the foundational tenancy layer that provides workspace isolation, user authentication, and feature access control.
+
+## Core Concepts
+
+### Tenant Hierarchy
+
+```
+User
+├── owns Workspaces (can own multiple)
+│   ├── has WorkspacePackages (entitlements)
+│   ├── has Boosts (temporary limit increases)
+│   ├── has Members (users with roles/permissions)
+│   ├── has Teams (permission groups)
+│   └── owns Namespaces (product boundaries)
+└── owns Namespaces (personal, not workspace-linked)
+```
+
+## Features
+
+- **Workspaces** - Primary tenant boundary (organisations, teams)
+- **Namespaces** - Product-level isolation within or across workspaces
+- **Entitlements** - Feature access control and usage limits
+- **User management** - Authentication, 2FA, and membership
+- **Teams** - Permission groups within workspaces
+
+## Installation
+
+```bash
+composer require host-uk/core-tenant
+```
