# Setting up the tutorial

This tutorial was written for version 1.6 (released on 28th June 2017).

Starting with version 1.6 VIATRA is available from the Simultaneous Release Train (Oxygen version: http://download.eclipse.org/releases/oxygen); for older releases or for older version use the release p2 repository at http://download.eclipse.org/viatra/updates/release/

Figure 1. Install window

For a faster installation, you may deselect the Contact all update sites during install... field, but then it might be necessary to install the required Xtext Runtime manually.

This document assumes that the CPS metamodels are installed into the Eclipse instance. They are available from the p2 repository https://hudson.eclipse.org/viatra/job/viatra-examples-cps/lastSuccessfulBuild/artifact/cps/releng/org.eclipse.viatra.examples.cps.update/target/repository/

VIATRA defines a custom perspective called `Transformation Development` that includes a few views and shortcuts that make it easier to develop queries and transformations. The remainder of the tutorial expects that this perspective is selected; in case a different perspective is used, the corresponding views and wizards are still available in their standard respective locations.
