Q: Where and how to place the megazine folder to make it work on a server
A: copy the whole folder as you downloaded it from our website to a subdirectory on your server. Like in this example:
I renamed the root folder to mz3-example in this case so I can have several different folders; like mz3v2alpha here.
The highlighted megazine.xml is the file that you modify and where you enter the elements like <page>, img>, ... to create the book with your pages.
You could/should add additional folders to hold you images (like the folder “img” in my case; or video or sound).
WIth version 2.0 you need the "js"-Folder at the right place; see here:

This megazine.xml is very simple and looks like this:
You can check the output in just following this link:
http://vservu.de/mz3-example/index.html or cut and paste it into your browser.
This is the example of my tutorial in YouTube about how to create a book in a fast way using the element “pages”:
http://www.youtube.com/watch?v=yQUxvTVBihQThe index.html is the slightly modified one from the download. I just corrected the path to point to the correct folder where megazine.xml is located: mz2-example
You also can check the other example under mz3v2alpha.
Here the index.html looks like this:

And if you follow the link you should see the book I created to test version 2.0 Alpha:
Hopefully these examples help you to get started with your own book!
