+# Kubernetes Installation Guide for Checkmate
+
+This guide walks you through deploying Checkmate on your Kubernetes cluster using Helm.
+
+## Prerequisites
+
+- A running Kubernetes cluster
+- Helm CLI installed and configured
+- `kubectl` configured to access your cluster
+
+## Steps
+
+### 1. Clone the repo and navigate to the Helm chart
+
+```bash
+git clone https://github.com/bluewave-labs/checkmate.git
+cd checkmate/charts/helm/checkmate
+```
+
+### 2. Customize values.yaml
+Edit `values.yaml` to update:
+- `client.ingress.host` and `server.ingress.host` with your domain names
+- `server.protocol` (usually http or https)
+- Secrets under the `secrets` section (`JWT_SECRET`, email credentials, API keys, etc.) — replace all change_me values
+
+### 3. Deploy the Helm chart
+```bash
+helm install checkmate ./charts/helm/checkmate
+```
+This will deploy the client, server, MongoDB, and Redis components.
+
+### 4. Verify the deployment
+Check pods and services:
+```bash
+kubectl get pods
+kubectl get svc
+```
+
+Once all pods are `Running` and `Ready`, you can access Checkmate via the configured ingress hosts.
