1) First link returns: server's 404 message.

Could you fix the permissions please.

2) Your "HowTo" articles start with "Make your own developer key".

If your directions are targeted at an audience who will be distributing their applications, would you please recommend using the developer key(s) that we supply here?

The reasons for that are best explained in the thread(s) on the "Combined Developer Keystore" topic here.

In general, the references to cowland are references to very old materials.
Most of that has been replaced with things you can find here (some in the top stickies).
In particular, the Jailbreak referenced on the cowland link does not work with the firmware version you are writing about, but there is one here for the K5 Paperwhite.

3) Credit where credit is due please.
