+# Keycloak Realm Configuration
+
+## Overview
+
+This directory contains the Keycloak realm configuration file (`dev-realm.json`) used by the Boilerplate. Keycloak is an **optional** open-source identity and access management solution that provides enterprise-grade authentication and authorization features.
+
+## What is Keycloak?
+
+Keycloak is a free, open-source identity server that provides:
+
+- **Centralized User Management**: Manage users, credentials, roles, and groups from a single location
+- **Single Sign-On (SSO)**: Allow users to authenticate once and access multiple applications
+- **Identity Brokering**: Integrate with external identity providers (LDAP, Active Directory, etc.)
+- **Fine-Grained Authorization**: Define and enforce complex access control policies
+- **Standards-Based**: Supports OpenID Connect, OAuth 2.0, and SAML 2.0 protocols
+
+## Keycloak in .NET Aspire
+
+When you run the Boilerplate project with .NET Aspire enabled (default configuration), Keycloak is automatically started as a containerized service. This provides a complete identity server for development and testing without any manual setup.
+
+The Keycloak container is configured in `Program.cs`:
+
+```csharp
+var keycloak = builder.AddKeycloak("keycloak", 8080)
+    .WithDataVolume()
+    .WithRealmImport("./Realms");
+```
+
+For more information, checkout .docs/07- ASP.NET Core Identity - Authentication & Authorization.md
