Talk:Moodle for Mobiles installation

Maybe I have Asperger's or something, but I need hyper-specific instructions for some things; the instructions read, "1. Add the following line to yourmoodledirroot/course/lib.php line 2 :"

Now what exactly does that mean? Does it mean append to line 2, make it the new line 2, or ...?

Thanks for any help on this. If someone could be so kind, could they show me exactly what the first few lines of that file should look like?

Thanks in advance any help on this.
