+# K8s Power Manager
+
+## Components
+1. **PowerManager Controller**: ensures the actual state matches the desired state of the cluster. 
+2. **PowerConfig Controller**: sees the powerConfig created by user and deploys Power Node Agents onto each node specified using a DaemonSet.
+   - powerNodeSelector: A key/value map used to define a list of node labels that a node must satisfy for the operator’s node
+     agent to be deployed.
+   - powerProfiles: The list of PowerProfiles that the user wants available on the nodes
+3. **Power Node Agent**: containerized applications used to communicate with the node’s Kubelet PodResources endpoint to discover the exact CPUs that
+    are allocated per container and tune frequency of the cores as requested
+
+
+## Setup 
+### 1. Manual
+
+Execute the following below **as a non-root user with sudo rights** using **bash**:
+1. Run the node setup script:
+    ```bash
+   git clone -b power_manager --depth=1 https://github.com/vhive-serverless/vhive.git
+    ./scripts/power_manager/setup_poer_manager.sh;
+
