+# Memcached
+
+Memcached is an in-memory key-value store for small chunks of arbitrary data, commonly used as a cache layer to speed up applications.
+
+## Dependencies
+
+None. Memcached is a standalone infrastructure service.
+
+## Configuration
+
+Key settings configured through your instance's `config.yaml`:
+
+- **memoryLimit** - Maximum memory usage (default: `64m`)
+- **maxConnections** - Maximum concurrent connections (default: `1024`)
+- **replicas** - Number of instances (default: `1`)
+
+## Usage
+
+Other apps that depend on Memcached (such as OpenProject) will connect to it automatically at `memcached.memcached.svc.cluster.local:11211`.
