 ## Adding an ADR Algorithm
 When the ADR Algorithm has been tested, and is ready for deployment, the ADR Algorithm has to be added to chirpstack. It is mandatory that the custom adr module is writtin in js.

 If the default `docker-compose.yml` file is used, the folder `./configuration/chirpstack` is already copied to `/etc/chirpstack` in the docker container.
-Therefore a new folder can be added such as `./configuration/chirpstack/adr-plugins` in which the js file can be added.
-This makes the file available at `/etc/chirpstack/adr-plugins/example-file.js` within the chirpstack container.

+### Helm
+
+When hosting via helm the steps are slightly different.
+
+1. Make sure that the persistent volume claim belonging to the chirpstack exists in your hosted setup.
+2. Find the actual name of the network-server pod. This can be done in a few ways. If you're have a connection via a GUI like `Lens` it can be found under the `Pods` list. If you're hosting on an Azure Kubernetes service, it can be found under the side menu `Workloads -> Pods`
+3. Use `kubectl` to copy the module into the pod
+   ```bash
+   kubectl cp ./path/to/module/adr-module chirpstack-xxxxxxxxx-xxxxx:/etc/chirpstack/adr-modules
+   ```
+4. Update `configmap.yaml` located under `/helm/charts/chirpstack/templates` with the path to the plugin under `[network]`, like this:
+   ```toml
+   [network]
+       adr_plugins=["/etc/chirpstack/adr-modules/example-file.js"]
+   ```
+   The first line already exists
+5. Once the helm chart has redeployed restart the network server to enable the new module.
