## Revision as of 15:53, 18 July 2018

This tutorial should make your start with Octopus a little easier. The tutorial will provide you with a couple of examples of different things that you can do with this program. It is by no means complete, and there are a lot of other things that Octopus can do for you, but hopefully it gives you an idea of how to use the different options. You can find more information in the online Manual. After doing the tutorial, you can look at the `testsuite` directory of Octopus which contains sample input files for various kinds of runs.

Note on MediaWiki error message you may get on some of these pages
