Keep in mind that these forums are user-driven forums. So, if you're looking for official documentation or tutorials, we might be able to help you... but they might not be the "official" reply from SmartBear. Your best bet is to contact SmartBear support to get their official stuff.
In the meantime.... start here.
This is the FULL set of documentation for TestComplete. There are tutorials documented in there as well. It's searchable with cross-references.
