Add languages as necessary. English is the source language for translations, all other languages are targets. Norwegian Bokmål is an example target language.
If you need a glossary, a lot of the terms are technical jargon, one is defined at mw:Help:Expect/Glossary.
There should be a template expect-gloss reading (with additional markup)
Please check out the [https://www.mediawiki.org/wiki/Special:MyLanguage/Help:Expect/Glossary glossary] and try to be consistent.
