+description: A Helm chart for deploying Pythnet price pusher
+# 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/)

+# This is the version number of the application being deployed. This version number should be

+# follow Semantic Versioning. They should reflect the version the application is using.
+# It is recommended to use it with quotes.

+# Helm Chart - Pyth Price Pusher
+this helm chart deploys the full stack components required to push cryptocurrency prices to the Pyth network. The chart supports setting up multiple chains with customized price configurations for each individual chain.
+
+# Usage
+
+TODO: update with pyth's usage instructions
+```
+helm repo add https://charts.keom.io
+helm upgrade --install pyth-pusher keom/pyth-pusher --namespace pyth --create-namespace --values values.yml
+```
+
+# Notes
+The resource allocations is relaxed to ensure smooth operations. Might improve in future versions
+
+# TODO
+- Move resource assignment to values.yml
+- Add monitoring stack to monitor gas prices and expenses
+- Alerts when pusher wallets passes a preset threshold
+- Ingress option to expose price-service for dapps
