How do I add additional translated items via the MediaWiki Universal Language Selector extension?

Question

I have added some contents to the MediaWiki sidebar (MediaWiki:Sidebar). When I changed the language from English to Malayalam using the Universal Language Selector, everything in the sidebar except the newly added contents got translated.

My questions:

1. What do I do to get all the sidebar contents to be translated to Malayalam?
2. Can I add those contents along with the translations to some file in the extension's folder so that it also will get translated?

As noted by Waldir:

• You should specify the link and the link label as system messages and create language code subpages of said messages for them to follow user interface language. See the manual for more. For instance * portal-url|portal with [[MediaWiki:Portal]] being "Portale" and [[MediaWiki:Portal/en]] "Portal" (on an Italian wiki).
• You can also use the Translate extension to translate the sidebar messages.
