You start out by saying there are two ways to import translations, then for
the first of those you say there are two ways of doing _that_, and you end
up sounding like Von Clausewitz(*).
How about just mentioning the "one-off import" option right in the first
section under the two bullet points, without an extra heading? That also
means you don't jump straight from the enumeration to the next subsection,
which always looks a bit like you're trying to simulate an index anyway.
