"Please copy this code, switch to your applications and paste it there"

Hi All,

I am trying to create a server in the Google App Engine. I have gotten to
the final step where we use "upload aggregate to app engine". After running
that code, I then got a success code in my browser that reads "Please copy
this code, switch to your applications and paste it there", but I cannot
find where in the application that I made to paste this to finish the
process. Any ideas?

Thanks,
Hannah
