Melange Installation In Eclipse

[Loungagna]

The website and this repo are scanty on installing melange within Eclipse.

After installing Text from the marketplace, attempts to install Melange, from the same marketplace fails with: Cannot complete the install because one or more required items could not be found. Software being installed: Melange SDK Feature 0.2.2.202011161009 (fr.inria.diverse.melange.sdk.feature.group 0.2.2.202011161009) Missing requirement: Melange Metamodel 0.2.0.201706292038 (fr.inria.diverse.melange.metamodel 0.2.0.201706292038) requires 'osgi.bundle; org.eclipse.xtext.xbase [2.7.0,2.11.0)' but it could not be found Missing requirement: Melange Metamodel 0.2.2.202011161009 (fr.inria.diverse.melange.metamodel 0.2.2.202011161009) requires 'osgi.bundle; org.eclipse.gemoc.dsl.model 0.0.0' but it could not be found Cannot satisfy dependency: From: Melange 0.2.2.202011161009 (fr.inria.diverse.melange 0.2.2.202011161009) To: osgi.bundle; fr.inria.diverse.melange.metamodel 0.1.0 Cannot satisfy dependency: From: Melange SDK Feature 0.2.2.202011161009 (fr.inria.diverse.melange.sdk.feature.group 0.2.2.202011161009) To: org.eclipse.equinox.p2.iu; fr.inria.diverse.melange [0.2.2.202011161009,0.2.2.202011161009]

So with a standard Java Developer Eclipse, and Text already installed, how does one install Melange, so that the tutorials can be followed?
