-Install following Eclipse environment:
-* GMF tooling see version http://download.eclipse.org/modeling/gmp/gmf-tooling/updates/releases-3.3.1a
-* the xtend2 extensions of GMF tooling.
-* xtend editor (to manage file encoding problem) http://download.eclipse.org/modeling/tmf/xtext/updates/composite/releases/

-It is recommended to run the generation in a second Eclipse Application launched from your running Eclipse instance.
-Add the following developer plugins to your workspace (first instance).

 === Papyrus Extension Root Node Description ===
+Since Papyrus for Eclipse 2021-09, the Papyrus Extension doesn't exist anymore, but its concepts have been included directly in the GMF metamodel. So this documentation is half-deprecated.

 ==== Compartment Visibility Preference ====
 Description : This extension allows to define the default visibility for the compartments. The compartments not referenced by this node are visible by default.
