go mod download
\`\`\`
### 3. Configure environment
\`\`\`bash
# Copy example environment file
cp .env.example .env
# Edit .env with your configuration
# Required variables:
# DATABASE_URL=postgresql://localhost/dbname
# API_KEY=your_api_key_here
\`\`\`
### 4. Initialize database (if applicable)
\`\`\`bash
# Run migrations
npm run migrate
# Or: python manage.py migrate
# Or: make migrate
\`\`\`
### 5. Verify installation
\`\`\`bash
# Run tests to verify setup
npm test
# Or: pytest
# Or: go test ./...
\`\`\`
Best practices:
Document how to run and use the project with executable examples:
For applications:
## Usage
### Running the application
\`\`\`bash
# Development mode with hot reload
npm run dev
# Production mode
npm start
# With custom port
PORT=8080 npm start
\`\`\`
The application will be available at `http://localhost:3000`
### Basic operations
**Create a new resource**:
\`\`\`bash
curl -X POST http://localhost:3000/api/resources \
-H "Content-Type: application/json" \
-d '{"name": "example", "value": 42}'
\`\`\`
**List all resources**:
\`\`\`bash
curl http://localhost:3000/api/resources
\`\`\`
For libraries:
## Usage
### Basic example
\`\`\`python
from project_name import Client
# Initialize client
client = Client(api_key="your_key")
# Perform operation
result = client.fetch_data(query="example")
print(result)
\`\`\`
### Advanced usage
\`\`\`python
# With custom configuration
client = Client(
api_key="your_key",
timeout=30,
retry_count=3
)
# Batch operations
results = client.batch_fetch([
{"query": "item1"},
{"query": "item2"}
])
\`\`\`
For CLI tools:
## Usage
### Basic commands
\`\`\`bash
# Show help
project-cli --help
# Run with default options
project-cli process input.txt
# Run with custom options
project-cli process input.txt --output result.txt --verbose
\`\`\`
### Common workflows
**Workflow 1: Data processing**
\`\`\`bash
# Step 1: Validate input
project-cli validate data.csv
# Step 2: Process data
project-cli process data.csv --format json
# Step 3: Export results
project-cli export results.json --format pdf
