+# Pulse Bridge Helm Chart
+
+A Helm chart for deploying Pulse Bridge - a comprehensive monitoring solution for HTTP services and databases.
+
+## Overview
+
+Pulse Bridge is a Go-based monitoring application that provides health checking capabilities for various services including HTTP endpoints, PostgreSQL, MySQL, MariaDB, Redis, and MSSQL databases. This Helm chart simplifies the deployment of Pulse Bridge on Kubernetes clusters.
+
+## Prerequisites
+
+- Kubernetes 1.16+
+- Helm 3.0+
+
+## Installation
+
+### Quick Start
+
+Install Pulse Bridge with your custom configuration:
+
+```bash
+helm install pulse-bridge ./pulse-bridge --set-file config.yaml=./my-config.yml
+```
+
+### Complete Installation with All Available Flags
+
+```bash
+helm install pulse-bridge ./pulse-bridge \
+  --set-file config.yaml=./my-config.yml \
+  --set replicaCount=2 \
+  --set image.repository=pulse-bridge \
+  --set image.tag=latest \
+  --set image.pullPolicy=IfNotPresent \
+  --set service.type=LoadBalancer \
+  --set service.port=8080 \
+```
+
+## Configuration
+
+### Configuration Parameters
+
+| Parameter | Description | Default |
+|-----------|-------------|---------|
+| `replicaCount` | Number of Pulse Bridge replicas | `1` |
+| `image.repository` | Docker image repository | `pulse-bridge` |
+| `image.tag` | Docker image tag | `latest` |
+| `image.pullPolicy` | Image pull policy | `IfNotPresent` |
+| `service.type` | Kubernetes service type | `LoadBalancer` |
+| `service.port` | Service port | `8080` |
+| `config.yaml` | Pulse Bridge monitoring configuration | See example below |
+| `resources` | Pod resource requests and limits | `{}` |
+| `nodeSelector` | Node labels for pod assignment | `{}` |
+| `tolerations` | Toleration labels for pod assignment | `[]` |
+| `affinity` | Affinity settings for pod assignment | `{}` |
+
+### Configuration File Structure
+
+Create a `my-config.yml` file with your monitoring targets:
+
+```yaml
+monitors:
+  # HTTP service monitoring
+  - name: "Web API Health Check"
+    type: "http"
+    interval: "30s"
+    timeout: "5s"
+    http:
+      url: "https://api.example.com/health"
+      method: "GET"
+      headers:
+        Content-Type: "application/json"
+        Authorization: "Bearer your-token"
+
+  # Database monitoring
+  - name: "PostgreSQL Database"
+    type: "database"
+    interval: "30s"
+    timeout: "10s"
+    database:
+      driver: "postgres"
+      connection_string: "postgres://user:password@db-host:5432/dbname?sslmode=disable"
+      query: "SELECT 1"
+
+  # Redis monitoring
+  - name: "Redis Cache"
+    type: "database"
+    interval: "15s"
+    timeout: "5s"
+    database:
+      driver: "redis"
+      host: "redis-host"
+      port: 6379
+      password: "redis-password"
+      database: "0"
+```
+
+## API Endpoints
+
+Once deployed, Pulse Bridge exposes the following endpoints:
+
+- `GET /health` - Application health check
+- `GET /monitor/services` - Status of all monitored services
+- `GET /monitor/services/{service-name}` - Status of a specific service
+
+## Upgrading
+
+```bash
+# Upgrade with new configuration
+helm upgrade pulse-bridge ./pulse-bridge --set-file config.yaml=./updated-config.yml
+
+# Upgrade with new image version
+helm upgrade pulse-bridge ./pulse-bridge --set image.tag=v1.1.0
+```
+
+## Uninstalling
+
+```bash
+helm uninstall pulse-bridge
+```
+
+## Troubleshooting
+
+### Check Pod Status
+
+```bash
+kubectl get pods -l app.kubernetes.io/name=pulse-bridge
