processing-js near release 0.1

For the last few days I tried to test my processing-js code however I couldn't push the code into my repos. The last steps in the instructions gave me an headache. I kept getting permission denied:

$git push origin master
permission denied .
fatal: the remote hung up unexpectedly.

I tried many times, still didn't work. May be I need to create very public key for each repos I have.

So I did tried to generate another key but I still got permission denied message. Well may be I need to dig deeper inside the documents.
