+The `k8s-sidecar` can also call the `node-red` api to install additional node modules (npm packages) before refreshing or importing the flow.json. Specifying a version for a module is supported (s. example below).
 You need to list your flows required 'NODE_MODULES' in the `sidecar.extraNodeModules`: e.g.
 
 ```yaml
 sidecar:
  extraNodeModules:
     - node-red-contrib-xkeys_setunitid
     - node-red-contrib-microsoft-teams-tasks
-    - node-red-contrib-json
+    - node-red-contrib-json@0.2.0
 ```
 To install the node modules successfully, the node red pod needs access to the `npmrc.registry` to download the declaired modules/packages.
