Two claims and two sources map 2 of 2, with claim 1 paired to source 1 and claim 2 paired to source 2.

Mapping is positional only and does not verify that a source actually supports its claim. Always read the source yourself before citing it.

How do I line claims up with sources?

Put one claim per line and the matching source on the same line number in the sources box.

What if I paste more claims than sources?

The extra claims are shown with no source pasted, so you can see exactly which claims still need one.
