If this is a one-off, I'd write a babel block like this and put it under 
the headline of that subtree:

#+NAME: tangle-and-export-readme
#+BEGIN_SRC emacs-lisp :tangle no :exports none
(org-babel-tangle)
(require 'ox-gfm)
(org-export-to-file 'gfm "README.md" nil t)
#+END_SRC


Then when you want to tangle,

C-c C-v g tangle-and-export-readme RET C-c C-c y

will do it. (Assuming contrib is on the load path, of course.)

You can use TAB completion with `C-c C-v g'.

HTH,
