+# WebHook Listener
+
+## Overview
+
+A service to listen GitHub webhooks and publish the data to NATS JetStream.
+
+## Setup
+
+### Prerequisites
+
+- **Python 3.x.x**
+- **Docker** for containerization
+
+## Environment Variables
+
+- `NATS_URL`: NATS server URL
+- `NATS_AUTH_TOKEN`: Authorization token for NATS server
+- `WEBHOOK_SECRET`: HMAC secret for verifying GitHub webhooks
+
+If you are using docker compose, you don't need to set NATS_URL for local development.
+
+Generate an AUTH TOKEN and Set the environment variable:
+
+```bash
+export NATS_AUTH_TOKEN=$(openssl rand -hex 48)
+```
+
+Set Webhook secret
+```bash
+export WEBHOOK_SECRET=
+```
+
+## Running with Docker Compose
+
+Build and run with Docker Compose:
+
+```bash
+docker-compose up --build
+```
+
+Service ports:
+- **Webhook Service**: `4200`
+- **NATS Server**: `4222`
+
+
+## Usage
+
+Configure your GitHub webhooks to POST to:
+
+```
+https://<server>:4200/github
+```
+
+### Event Handling
+
+Events are published to NATS with the subject:
+
+```
+github.<owner>.<repo>.<event_type>
+```
+
+
+
+## Setup for Local Development
+### Installation
+
+Install dependencies:
+
+```bash
+pip install -r requirements.txt
+```
+
+### Running Service
+
+
+```bash
+fastapi dev #For Development
+fastapi run #For Production
+```
+
+### Important Notes
+
+- The service automatically sets up a NATS JetStream stream named `github` to store events.
+- Ensure your firewall allows traffic on port 4222 (NATS).
+- Authentication tokens are crucial for securing the NATS server and ensuring only authorized clients can connect.
+- The webhook listener service connects to the NATS server like any other client using the specified URL and token.
