# Makefile Formatting

## Instructions

When writing or modifying Makefiles, follow these formatting guidelines:

1. Each target should have a `.PHONY` declaration
2. Format should follow this pattern:
   - `.PHONY: target-name` on its own line
   - `target-name:` on the next line
   - Commands indented with a tab
   - Empty line between targets

## Example

```makefile
.PHONY: foo
foo:
	@echo 'foo'

.PHONY: bar
bar:
	@echo 'bar'
```

## When to Use

Apply these guidelines when:
- Creating new Makefile targets
- Modifying existing Makefiles
- Reviewing Makefile code
