Looks good! Can I make one small suggestion, though? Could you change
the following paragraph to use fewer technical terms?

<step><para>For security reasons, you will next need to authenticate
this software repository using a <emphasis>GPG key</emphasis>.  GPG is
an algorithm which allows individuals to encrypt and digitally sign
messages and data.  The GPG key should be available for download on the
software repository's website.</para>

Terms like authenticate, algorithm and encrypt/digitally sign seem a
little too technical for what I'd imagine the target audience to be.
After that, it looks pretty much spot on.

Thanks,

Phil
