In the previous part, we added a master page header to to every page and used this to split the ePub.
Now we are unpacking the ePub and after creating a local Dreamweaver site, we edit the various files inside the ePub package.
Note that I am using a MAC with the latest OS (Mavericks) to do this work. This makes life easier since I can view the ePub file with Apple's iBooks app.
If you are working with a PC/Windows, then you can test the ePub with Readium within the Google Chrome browser.
Addendum: To make sure that the header (originally only on the master pages), will appear above the main text, make the header text box very wide so that it is the first item reading left to right. The articles will then put things in the correct order reading from top left.
