How to update documentation on ipxe.org/docs?

[soltesz]

Hello, I would like to update the "Notes" section of http://ipxe.org/cmd/imgfetch.

Specifically, I would like to add a clarifying comment that when the "pathname" argument is given to initrd that all subdirectories of the path must already exist for the file to be available at run time (i.e. subdirectories are not created automatically).

Also, I would like to add a comment describing the "mode=" option to initrd files. This is helpful for introducing custom init scripts that must be executable.

I tried to register on the ipxe.org wiki but, it always reports a CAPTCHA error even though I'm sure I was entering the correct value.

What can I do differently?

Thank you!
