+# PackagePulse Quick Start Guide
+
+This guide will help you quickly set up and run PackagePulse MCP server for vulnerability scanning and package health analysis.
+
+## Prerequisites
+
+- **Go 1.24.3 or higher** - Required for building the project
+- Terminal/Command line access
+
+## Installation
+
+### 1. Clone the Repository
+
+```bash
+git clone https://github.com/rayprogramming/PackagePulse.git
+cd PackagePulse
+```
+
+### 2. Install Dependencies
+
+```bash
+go mod download
+```
+
+### 3. Build the Project
+
+```bash
+go build -o PackagePulse
+```
+
+This will create a `PackagePulse` binary in your current directory.
+
+## Running PackagePulse
+
+### Basic Usage
+
+PackagePulse runs as an MCP (Model Context Protocol) server using stdio transport:
+
+```bash
+./PackagePulse
+```
+
+The server will start and communicate via stdin/stdout, ready to accept MCP protocol messages.
+
+### Using with MCP Inspector
+
+To test the server interactively, use the official MCP Inspector:
+
+```bash
+npx @modelcontextprotocol/inspector ./PackagePulse
+```
+
+### Using with MCP Clients
+
+Configure your MCP client (e.g., Claude Desktop, VSCode extensions) to connect to PackagePulse:
+
+**Example Claude Desktop configuration** (`claude_desktop_config.json`):
+
+```json
+{
+  "mcpServers": {
+    "packagepulse": {
+      "command": "/path/to/PackagePulse/PackagePulse"
+    }
+  }
+}
+```
+
+## Available Features
+
+PackagePulse provides the following MCP tools:
+
+### 1. Vulnerability Scanning (`vulns`)
+Check packages for known security vulnerabilities using OSV database.
+
+**Example:**
+```json
+{
+  "ecosystem": "npm",
+  "package": "lodash",
+  "version": "4.17.19"
+}
+```
+
+### 2. Package Health Analysis (`health`)
+Analyze package maintenance status, update frequency, and overall health.
+
+**Example:**
+```json
+{
+  "ecosystem": "npm",
+  "package": "express"
+}
+```
+
+### 3. License Information (`license`)
+Retrieve SPDX license details, compatibility, and categorization.
+
+**Example:**
+```json
+{
+  "license_id": "MIT"
+}
+```
+
+### 4. Upgrade Planning (`upgrade-plan`)
+Generate smart upgrade recommendations based on vulnerabilities and package health.
+
+**Example:**
+```json
+{
+  "ecosystem": "npm",
+  "package": "lodash",
+  "current_version": "4.17.19"
+}
+```
+
+## Development
+
+### Running Tests
+
+```bash
+go test -v ./...
+```
+
+**Note:** Some tests require network access to external APIs (OSV, deps.dev). They may fail in restricted environments but this is expected.
+
+### Linting
+
+```bash
+go vet ./...
+```
+
+For comprehensive linting with golangci-lint:
+
+```bash
+# Install golangci-lint
+go install github.com/golangci/golangci-lint/cmd/golangci-lint@latest
+
+# Run linter
+golangci-lint run ./...
+```
+
+### Local Development
+
+For active development, you can run the server directly:
+
+```bash
+go run main.go
+```
+
+## Troubleshooting
+
+### Binary Not Found
+If you get "command not found" after building:
+- Make sure you're in the correct directory
+- Use `./PackagePulse` (with `./` prefix) on Unix/Linux/macOS
+- Use `PackagePulse.exe` on Windows
+
+### Build Failures
+If `go build` fails:
+- Verify your Go version: `go version` (must be 1.24.3+)
+- Ensure dependencies are downloaded: `go mod download`
+- Try cleaning the build cache: `go clean -cache`
+
+### Connection Issues
+If the MCP client can't connect:
+- Verify the binary path in your client configuration
+- Check that the binary has execute permissions: `chmod +x PackagePulse`
+- Review client logs for specific error messages
+
