Because of the image in that repo the link does not jump exactly to the right location... anyway the tips are just below that image/animation.
Also, for some reason the link to my repo failed... so here it is again (well it just links to the same page as the tips link)

Ha! Well not too much response here...

Anyway @Pedro:
So I do not have too much time to work on an updated template. But I have added a somewhat updated template file to my emacs-lisp repo here along with some handy tips.
Then of course you can further just check out examples of other ob-....el files. Hope this is useful.
