How to Add tooltip to action registered using @ActionRegistration

I used the Netbeans wizard to create an action to use in my editor pane, but cannot see how to set a tooltip for this action.  I can see that all the other actions in the editor pane have tooltips.  How can I set the tooltip:

/*
* To change this license header, choose License Headers in Project Properties.
* To change this template file, choose Tools | Templates
* and open the template in the editor.
*/
package org.ihc.cem.ceml.cedar.modules.editor.actions;

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import org.openide.awt.ActionID;
import org.openide.awt.ActionReference;
import org.openide.awt.ActionReferences;
import org.openide.awt.ActionRegistration;
import org.openide.cookies.EditorCookie;
import org.openide.util.NbBundle;

@ActionID(
        category = "Edit",
        id = "org.ihc.cem.ceml.cedar.modules.editor.actions.CompileWithTerminology"
)
@ActionRegistration(
        iconBase = "org/ihc/cem/ceml/cedar/modules/editor/resources/compileAll.gif",
        displayName = "#CTL_CompileWithTerminology"
)
@ActionReferences({
    @ActionReference(path = "Editors/text/x-cem/Toolbars/Default", position = 4500, separatorBefore = 4490)
})
@NbBundle.Messages("CTL_CompileWithTerminology=Compile with Terminology Validation")
public final class CompileWithTerminology implements ActionListener {

    private final EditorCookie context;

    public CompileWithTerminology(EditorCookie context) {
        this.context = context;
    }

    @Override
    public void actionPerformed(ActionEvent ev) {


    }
}
