Description of feature

Hi Chris,
I am using demo pipeline to introduce students to Nextflow. So, i run one test using Github Codespace (from Nextflow Training) and that was fine to run -profile test. But, when i try to run the example from pipeline Demo site, there is a error both from memory and cpus limitations.
I think that if we put some params to limitate the amount this will run fine.

What you think about that?
