+# Redis
+
+Redis is an open-source, in-memory data structure store used as a database, cache, and message broker. This deploys a shared Redis instance used by apps that require it.
+
+## Dependencies
+
+None. Redis is a standalone infrastructure service.
+
+## Configuration
+
+Key settings configured through your instance's `config.yaml`:
+
+- **port** - Service port (default: `6379`)
+
+## Usage
+
+Apps that depend on Redis (such as Immich, Mastodon, Discourse, and others) will connect to it automatically at `redis.redis.svc.cluster.local:6379`. Authentication is managed through the secrets system.
