+
+Valkey can be configured automatically using Devbox's built in Valkey plugin. This plugin will activate automatically when you install Valkey using `devbox add valkey`
+
+[**Example Repo**](https://github.com/jetify-com/devbox/tree/main/examples/databases/valkey)
+
+[![Open In Devbox.sh](https://www.jetify.com/img/devbox/open-in-devbox.svg)](https://devbox.sh/open/templates/valkey)
+
+## Adding Valkey to your shell
+
+`devbox add valkey`, or in your Devbox.json
+
+```json
+    "packages": [
+        "valkey@latest   "
+    ],
+```
+
+This will install the latest version of Valkey. You can find other installable versions of Valkey by running `devbox search valkey`. You can also view the available versions on [Nixhub](https://www.nixhub.io/packages/valkey)
+
+## Valkey Plugin Details
+
+The Valkey plugin will automatically create the following configuration when you install Valkey with `devbox add`
+
+### Services
+
+* valkey
+
+Use `devbox services start|stop [service]` to interact with services
+
+### Helper Files
+
+The following helper files will be created in your project directory:
+
+* \{PROJECT_DIR\}/devbox.d/valkey/valkey.conf
+
+
+### Environment Variables
+
+```bash
+VALKEY_PORT=6379
+VALKEY_CONF=./devbox.d/valkey/valkey.conf
+```
+
+### Notes
+

+
+You can manually start Valkey in the foreground by running `valkey-server $VALKEY_CONF --port $VALKEY_PORT`.
+
