The AutoVue group hosts their documentation on the Oracle Technology Network (OTN) website, similar to many other Oracle groups. Here is a link to the main AutoVue docs page (which covers all products, AutoVue, VueLink, Document Print Services, etc): http://www.oracle.com/technetwork/documentation/autovue-091442.html
In terms of other useful links, I would recommend to look at the AutoVue "Product Information Center" (PIC), which is authored by our Support team, and is in the knowledge base inside the My Oracle Support portal. Here is a link to the AutoVue PIC (requires login to MOS portal): https://support.oracle.com/CSP/main/article?cmd=show&type=NOT&doctype=BULLETIN&id=1340763.1
Hope this helps.
