+----------------------------------------------
+Autogenerated from chart metadata using [helm-docs v1.5.0](https://github.com/norwoodj/helm-docs/releases/v1.5.0)
+
+
+Docker repository and tag are required. Helm install example:
+```
+helm install feast-python-server . --set image.repository=REPO --set image.tag=TAG
+```
+
+Deployment assumes that `feature_store.yaml` exists on docker image. Example docker image:
+```
+FROM python:3.7
+
+RUN apt update && \
+    apt install -y jq
+
+RUN pip install pip --upgrade
+
+RUN pip install feast
+
+COPY feature_store.yaml /feature_store.yaml
+```
+
+Make sure that you have enabled the flags for the python server. Example `feature_store.yaml`:
+```
+project: feature_repo
+registry: data/registry.db
+provider: local
+online_store:
+    path: data/online_store.db
+flags:
+  alpha_features: true
+  python_feature_server: true
+```
