Hi folks!
My new installation of xwiki 11.10.2+1 on debian 10 works fine, it was installd from official repo.
Fresh installed wiki page http://xwiki:8080/xwiki/bin/view/Help/Videos/ shows me a links to tutorial videos recorded in 2012. But you already have more recent videos - at page https://www.xwiki.org/xwiki/bin/view/Documentation/UserGuide/ I see links to videos of 2016 year. I think it will be better for new users to have link to the videos of 2016 year in a fresh installation.
Thank you!
