+## Redis Object Cache

+After first `docker compose up`, install the **Redis Object Cache** plugin in WP Admin:
+1. Plugins → Add New → search "Redis Object Cache" (by Till Krüss)
+2. Install & Activate
+3. Settings → Redis → "Enable Object Cache"
+
+The `wp-config.php` already has the `WP_REDIS_HOST` and `WP_REDIS_PORT` constants set.
