+# 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.

+# to the chart and its templates, including the app version.
+# Versions are expected to follow Semantic Versioning (https://semver.org/)

+# Install NetworkPolicy adapter
+
+> [!Note]
+> The `nimbus-netpol` adapter leverages
+> the [network plugin](https://kubernetes.io/docs/concepts/extend-kubernetes/compute-storage-net/network-plugins/)
+> for its functionality.
+> To use this adapter, you must be using a networking solution which supports NetworkPolicy.
+
+Install `nimbus-netpol` adapter using Helm charts locally (for testing)
+
+```bash
+cd deployments/nimbus-netpol/
+helm upgrade --install nimbus-netpol . -n nimbus
