	=== HELP ===
	To avoid you to install Go, the build is made by podman or docker.
	
	Installinf (you can use local Go by setting GO=local)):
	# use podman or docker to build
	$$ make install
	# or use local Go
	$$ make install GO=local
	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, one more time you can use local Go by setting GO=local:
	$$ make build
	$$ 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 binaries
	EOF
