+description: A Helm chart for Kubernetes
+
+# A chart can be either an 'application' or a 'library' chart.
+#
+# Application charts are a collection of templates that can be packaged into versioned archives
+# to be deployed.
+#
+# Library charts provide useful utilities or functions for the chart developer. They're included as
+# a dependency of application charts to inject those utilities and functions into the rendering
+# pipeline. Library charts do not define any templates and therefore cannot be deployed.
+type: application
+
+# This is the chart version. This version number should be incremented each time you make changes
+# to the chart and its templates, including the app version.
+# Versions are expected to follow Semantic Versioning (https://semver.org/)
+version: 0.1.0
+
+# This is the version number of the application being deployed. This version number should be
+# incremented each time you make changes to the application. Versions are not expected to
+# follow Semantic Versioning. They should reflect the version the application is using.
+# It is recommended to use it with quotes.
+appVersion: "v5.27.1"

+# Helm Chart 
+
+## Limitation
+osrm-extract use allot of memory and if it doesn't have enough the init container will crash and the deployment will fail. Depending on the dataset you are using make sure your pod has enough memory to process the freshly new data it's pulling on deployment.
+
+## Configuration
+Configure your ingress, PVC and settings depending on the dataset you need.
+Configuring your PVC with a delete claim policy is recommended if you want to pull the latest dataset when you deploy a new version.
+Configuring cors origins to your apps is suggested if you want to avoid the public using your resources.
+
+> Copy the `values.override.example.yaml` file and rename it to `values.override.yaml`
+> It's preferable using the `values.override.yaml` so you can always pull a future version of the chart without overriding your configuration.
+
+## Debug
+```bash
+helm template osrm-backend .
+```
+
+## Install
+```bash
+helm install osrm-backend . -f values.override.yaml -n osrm
+```
+
+> Warning! Currently upgrading is not working properly because the new pod tries to attach to the same PVC as the current container. This need to be improved!
+
+## Update
+```bash
+helm upgrade osrm-backend . -f values.override.yaml -n osrm
+```
+
+## Uninstall
+```bash
+helm uninstall osrm-backend -n osrm
+```
+
+check init containers status
+```bash
+kubectl logs <pod-id> -c <container-name> -n osrm -f
+```
+
+default init containers
+```
+osrm-download
+osrm-init
+```
+
+check logs of the running pod
+```bash
+kubectl logs <pod-id> -n osrm -f
+```
+
+## Improvements
+- [ ] Allow multiple init container configuration to process multiple `.osm.pbf` files
+- [ ] Make PVC Dynamic per release to allow upgrading the helm chart (this also make sure to pull the latest datasets)
