Docs unclear

Hi,

This doesn't quite work as intended:

Starting from no folder at all:

	# git submodule add https://github.com/cnlohr/rawdrawandroid
	# git submodule update --init --recursive
	# make my-release-key.keystore
	# cp rawdrawandroid/AndroidManifest.xml .

Do I clone this repo first? Do I make an empty directory, initialize it as a git repo, then do the above? (In which case the make command doesn't make sense... is it missing "-C rawdrawandroid" maybe?
