What have you tried?

The first few links found here:

seem pretty easy to understand. It's a very short and simple licence,
precisely because it puts very few requirements on you. If you are using
Library X (which is under the BSD-3 licence) then all you need do to meet
the licence requirements is to include Library X's copyright notice and
licence. You don't have to provide the source code to Library X, or to your
own application.
