Install PageMaster as any other module:
upload its files in the proper locations
(there's needed the livepipe.net library in the /javascript folder)
and the usual folder in /modules.

Go to your Modules Admin Panel and regenerate the list,
install, activate and configure the writable folder path
that pagemaster will use when need to upload files to the site,
and that's all, begin the creation of your publication types
and manage your stuff ;-)


Some things you should know for using PageMaster:

workflow: "none"
- all users can add new publications to the publication type 
  if they own the ACCESS_COMMENT permission in zikula

general:
- if you are using the file upload possibility of pagemaster
  there will be thumbnails created by the Thumbnail module.
  The Thumbnail module needs at least the permission
  ACCESS_EDIT to create Thumbnails. So - do not forget to
  give this permission to the user group that should be able
  to upload image files.

Enjoy!
