Extensive help on how to use a particular tool in Galaxy is often included on the tool page itself, inside Galaxy. To see this help, click on a tool in the left tool panel, and then scroll to the bottom of the center panel. Help includes parameter explanations, links to the tool developer's help pages, and examples.
This page links to supplementary information about tools. This information is important/useful enough to record in a permanent place, but not important/useful enough to include on the tool pages themselves. For general help on using Galaxy, see Learn.
