Greetings, I've never used this tool but you may have to perform some sort of configuration to setup such things. The Geany website has a section on support including an IRC channel and mailing list, as well as the manual. As for videos I know of http://learn.perl.org/first_steps/ and http://perlmaven.com/beginner-perl-maven-video-course, but have not used them personally. You may want to look at Getting Started with Perl from the Tutorials section of this site.
