Generate a Makefile
A Makefile defines named commands, called targets, that you run with the make tool, giving a project a consistent set of shortcuts such as build, test and clean. This generator turns a simple list of target names and their commands into a proper Makefile. It declares all the targets as .PHONY, which tells make they are commands rather than files, and adds a help target that lists the available commands, a convenient convention.
Each command is indented with a tab, which make strictly requires, avoiding a classic Makefile mistake.
Consistent project commands
Makefiles are a simple, universal way to standardise common tasks across a project, so every developer runs the same build, test and deployment commands regardless of the underlying tools. They work on virtually any Unix-like system without extra dependencies, which is why they remain popular even in projects built with modern languages. A help target makes the available commands discoverable.
The .PHONY declaration prevents make from being confused by a file that happens to share a target's name. Review the output and expand it with variables and dependencies as your project grows. All generation happens locally in your browser.

Frequently Asked Questions
What does .PHONY do?
It tells make that the targets are commands, not files, so make always runs them even if a file with the same name exists.
Why must commands use a tab?
Make strictly requires command lines to be indented with a real tab character, not spaces. The generator uses tabs to avoid this common error.
What is the help target for?
It lists the available commands, a common convention that makes a Makefile self-documenting so developers can discover what they can run.
Can I add variables and dependencies?
Yes. This generates a starting Makefile; you can add variables, prerequisites between targets and more advanced make features by hand.
