	=== HELP ===
	To avoid you to install Go, the build is made by podman or docker.
	
	You can use:
	$$ make install
	This will build and install katenary inside the PREFIX(/bin) value (default is $(PREFIX))
	
	To change the PREFIX to somewhere where only root or sudo users can save the binary, it is recommended to build before install:
	$$ make build
	$$ sudo make install PREFIX=/usr/local
	
	Katenary is statically built (in Go), so there is no library to install.
	
	To build for others OS:
	$$ make build GOOS=linux GOARCH=amd64
	This will build the binary for linux amd64.
	
	$$ make build GOOS=linux GOARCH=arm
	This will build the binary for linux arm.
	
	$$ make build GOOS=windows GOARCH=amd64
	This will build the binary for windows amd64.
	
	$$ make build GOOS=darwin GOARCH=amd64
	This will build the binary for darwin amd64.
	
	Or you can build all versions:
	$$ make build-all
	EOF
