Finally you must add the i18n keys to the package you used in your velocity page. There is one i18n key that you must add that you probably don't use in your help page but is required by the context help system: the help page title. The name for the key must follow this scheme:

chelp.pagename.title Example: chelp.grp-BuddyGroup-des.title

You must also add the i18n key you used in the context help launcher as hover text, in our example above this was chelp.hover.bgDetail-BuddyGroup.

In our example you have to add those to the files located under CLASSPATH/org/olat/group/ui/edit/_i18n/*.
