Before using both client or server, install the uuid php pear library, it handle UUID generation in a nice and really fast way.
If you don't install this extension, the module will generate random time-based series of numbers instead of standard V4 UUID.
Note that that it should not alter module behavior, just consider installing this php extension will force the module to use standardised UUID's.
At pull time, when updating an existing node, the last known revision will be updated.
Numerous dependencies are optional, but can give you great things, you should consider install:
PHP-UUID pear extention, that will generate V4 UUID for entities.
MimeDetect Drupal module, that will allow some finer mime type detection for file. If you are using the FileField module, Yamm will override this module's mime detection using its own.
You are going to experience some problems with files, we don't support any file module right now.
If you use image_attach, it will result in image id pointing to nothing, the only provided support is for the filefield module, and it suffers from lack of testing.
Right now, only the default profile is used to pass data to client at pull time, we are going to work on enabling different profile at the same time, for each client.
