# Prerequisites[¶](https://knowledge.dataiku.com/latest/courses/crash-course/dss9/what-youll-need.html#prerequisites "Permalink to this headline")

To do the hands-on exercises in this crash course, you’ll need access to an instance of Dataiku DSS 9.

* To build the model fairness report, the instance must have the Model Fairness Report plugin installed.

* To deploy projects with the Deployer, you need access to an Automation node.

* To use the wiki export, the DSS instance must be set up to export to PDF.

* To use the Git integration for notebooks, the DSS instance must be set up to work with git remotes.

* To do time series forecasting, you will need a Dataiku DSS instance with the Time Series Preparation and Time Series Forecast plugins installed.

If you don’t have a DSS 9 instance readily available, you can download the free edition, or start a 14-Day Free Online Trial. To get the free edition or start a hosted trial, visit the Dataiku website and click Get Started in the top right to see the different options.

If you are using the hosted trial, and you need more time to complete the course, you can request an extension using the intercom widget that is available on the lower right corner of every DSS home page.
