cd gator
go build -o gator

The setup.sh script provides several options for different use cases:

./setup.sh          # Complete setup (default)
./setup.sh setup    # Complete setup
./setup.sh db       # Database setup only
./setup.sh migrate  # Run migrations only
./setup.sh config   # Create config file only
./setup.sh install  # Install gator binary only
./setup.sh help     # Show help message

To run migrations manually:

# Up migrations
goose -dir sql/schema postgres "your_db_url" up

# Down migrations
goose -dir sql/schema postgres "your_db_url" down
