+# 🚀 Quick Start Guide to Contributing to Gin
+
+Welcome! This guide will help you get started contributing to the Gin Web Framework.
+
+## ✅ Environment Setup Complete
+
+Your development environment is ready:
+- **Go Version**: 1.25.0 ✓ (requires 1.24+)
+- **Dependencies**: All modules verified ✓
+- **Dev Tools**: golint and misspell installed ✓
+- **Tests**: All passing (99.1% coverage) ✓
+
+## 📚 Understanding the Project Structure
+
+### Core Files
+- **`gin.go`** - Main engine and router
+- **`context.go`** - Request/response context handling
+- **`routergroup.go`** - Route grouping and middleware
+- **`tree.go`** - High-performance routing tree (radix tree)
+- **`logger.go`** - Logging middleware
+- **`recovery.go`** - Panic recovery middleware
+
+### Important Directories
+- **`binding/`** - Request data binding (JSON, XML, YAML, forms, etc.)
+- **`render/`** - Response rendering (JSON, XML, HTML, etc.)
+- **`internal/`** - Internal utilities (not public API)
+- **`examples/`** - Usage examples
+
+## 🎯 How to Contribute
+
+### 1. Find Something to Work On
+
+**Good First Issues:**
+- Check [GitHub Issues](https://github.com/gin-gonic/gin/issues?q=is%3Aissue+is%3Aopen+label%3A%22good+first+issue%22)
+- Look for issues labeled "good first issue" or "help wanted"
+- Browse [Discussions](https://github.com/gin-gonic/gin/discussions) for feature ideas
+
+**Areas You Can Help:**
+- 🐛 Fix bugs
+- 📝 Improve documentation in `docs/doc.md`
+- ✨ Add new features
+- 🧪 Improve test coverage
+- ⚡ Performance optimizations
+- 🌐 Translate documentation
+
+### 2. Development Workflow
+
+**Before Starting:**
+```bash
+# Create a new branch for your work
+git checkout -b feature/my-contribution
+```
+
+**Make Your Changes:**
+```bash
+# Format your code (required)
+make fmt
+
+# Run tests
+make test
+
+# Check for common issues
+make vet
+
+# Check formatting (CI will run this)
+make fmt-check
+
+# Fix misspellings
+make misspell
+```
+
+**Run Specific Tests:**
+```bash
+# Test a specific package
+go test -v ./binding/
+
+# Test a specific function
+go test -v -run TestContextQuery
+
+# Run with race detector
+go test -race ./...
+```
+
+### 3. Code Standards
+
+**Important Rules:**
+- ✅ All tests must pass
+- ✅ Code must be formatted with `make fmt`
+- ✅ Add tests for new features
+- ✅ Update `docs/doc.md` for new features (NOT README.md)
+- ✅ Keep commits focused and atomic
+- ✅ Squash to max 2 commits before submitting PR
+
+**Example Test Pattern:**
+```go
+func TestMyNewFeature(t *testing.T) {
+    // Setup
+    router := gin.New()
+    
+    // Test your feature
+    w := httptest.NewRecorder()
+    req, _ := http.NewRequest("GET", "/test", nil)
+    router.ServeHTTP(w, req)
+    
+    // Assert
+    assert.Equal(t, 200, w.Code)
+}
+```
+
+### 4. Submit Your PR
+
+**Checklist:**
+- [ ] Tests pass locally (`make test`)
+- [ ] Code is formatted (`make fmt`)
+- [ ] No linting errors (`make vet`)
+- [ ] Documentation updated (if needed)
+- [ ] Commits squashed to ≤2 commits
+- [ ] PR targets `master` branch
+- [ ] PR description explains what and why
+
+**PR Template Will Ask:**
+- What does this PR do?
+- Why is this change needed?
+- How has this been tested?
+- What issues does it fix? (use `Fixes #123`)
+
+## 🛠️ Common Development Tasks
+
+### Running the Examples
+```bash
+cd examples/
+go run <example-name>/main.go
+```
+
+### Checking Code Coverage
+```bash
+make test
+# coverage.out file will be generated
+go tool cover -html=coverage.out
+```
+
+### Testing Against Different Go Versions
+```bash
+# The project supports Go 1.24+
+# Make sure your changes work with that version
+```
+
+### Debugging Tips
+```bash
+# Enable debug mode
+export GIN_MODE=debug
+
+# Run with verbose output
+go test -v -run TestName
+```
