Documentation on "dictionary" needed.
Message documentation should clarify the term "dictionary" - it is very unlikely that one is asked to grab a dictionary out of her bookshelf and to insert it into the field on her screen ;-)
- zeroconfig-lang name overrides ("[[:MediaWiki:Zeroconfig-lang name overrides/en]]")
- zeroconfig-name ("[[:MediaWiki:Zeroconfig-name/en]]")
- zeroconfig-banner ("[[:MediaWiki:Zeroconfig-banner/en]]")
Likely a specific input format is meant, such as: "Language code" colon "String" - but which?
Maybe, when "dictionary" it too lengthy to explain, it might be a link to a help page in the original messages?
