If you followed all the recommendations of the two previous sections, you are now ready to insert your first item; if you didn't go back and execute all the steps before going further.
In the Add a new document page you have to fill in at least the title, but an item without a file is useless, because it can't contain any useful information, so, normally you would add at least a file too.
If an item is inserted without attaching any object it won't trigger any event, but if one object is attached it will trigger an event called doc_newobj. If this event is active in the message center, it will send an email to any people subscribed to this event, refer to the message center documentation for further details. Normally people subscribed to this kind of event will be the ones responsible for approving it.
