What needs to be improved?

It would be nice if some of the missing xPDO constants were explained. I'd do it, but I'm not sure of how many of them work.

UPDATE_OBJECT - Well described in the current docs, but this used to also mean the object would not be uninstalled. I'm not sure if it still does.

PRESERVE_KEYS - I assume this doesn't apply to autoincrement keys, only to text keys like Contexts, but it should probably say so.

I think I know what these would do, but I'm not sure, and they're missing from the list:

ABORT_INSTALL_ON_VEHICLE_FAIL
UNINSTALL_OBJECT

I have no idea what these do:

RESOLVE_FILES
RESOLVE_FILES_REMOVE
RESOLVE_PHP
PREEXISTING_MODE
REMOVE_PREEXISTING
RESTORE_PREEXISTING
