A little help please regarding translation

I'm translating dolphin 6 to Swedish and I was wondering what part should be translated, for example : '_contact' => 'your contact information here'. What part should be translated?

'_contact' => 'your contact information here'

You just need to translate the part highlighted in red, the first part is the Language key.. :)

You should also be  adding/editing new languages from Admin Panel - Settings - Language Settings.
