Translating on git rep - question about *unfinished* type

i was exploring translation files, and i have seen this:
<translation type="unfinished"></translation>

could you tell me more about that?
can i just remove the type property and insert a translation?

This is actually an attribute set automatically by the tool Qt Linguist that generated the .ts file. If you think the translation is done and is correct, you can just remove that kind of lines.
