+# Vald Agent
+
+<!-- introduction sentence -->
+
+⚠ This image is under developing and runs incorrectly.
+
+`vald-agent` is the docker image for the vald-agent component.
+
+This image is responsible for the following:
+
+- Store index data along with the user request.
+  - The store destination is In-Memory, Volume Mounts, Persistent Volume, or External Storage(⚠).
+- Search the nearest neighbor vectors of the request vector and return the search result.
+
+⚠ When you'd like to use the external storage, it requires [vald-agent-sidecar](https://hub.docker.com/r/vdaas/vald-agent-sidecar/tags?page=1&name=latest) on the Kubernetes cluster.
+
+For more details, please refer to the [component document](https://vald.vdaas.org/docs/overview/component/agent).
