+
+CodeGate is a local gateway that makes AI agents and coding assistants safer.
+
+## TL;DR
+
+```console
+helm repo add codegate []
+
+helm install codegate/codegate
+```
+
+## Usage
+
+The Codegate Chart is available in the following formats:
+- [Chart Repository](https://helm.sh/docs/topics/chart_repository/)
+- [OCI Artifacts](https://helm.sh/docs/topics/registries/)
+
+### Installing from Chart Repository
+
+The following command can be used to add the chart repository:
+
+```console
+helm repo add codegate []
+```
+
+Once the chart has been added, install one of the available charts:
+
+```console
+helm install codegate/codegate
+```
+
+### Installing from an OCI Registry
+
+Charts are also available in OCI format. The list of available charts can be found [here](https://github.com/stacklok/codegate-helm/charts).
+Install one of the available charts:
+
+```shell
+helm upgrade -i <release_name> oci://ghcr.io/stacklok/codegate-helm/codegate --version=<version>
+```
