How can I schedule a Demo for Portfolio?

[Steven F Behnke]

Atlassian offers documentation and introduction materials for their products – https://www.atlassian.com/software/jira/portfolio/demo

They also have a service called Atlassian University – https://www.atlassian.com/university

You're probably going to have to find a local expert to perform actual demo's or training though – https://www.atlassian.com/resources/experts/
