[boost.QVM] can you explain quaternions in the docs?

Hi Everyone,
I landed on this library docs when trying to learn what quarterions are
for. Although the library has a vast documentation it doesn't explain what
quaternions are and why they are used. When I was taught algebra for the
purpose of computer graphics, vectors and matrices were on the table, but
no quaternions. The examples show that I need to create a quaternion only
to turn it into a rotation matrix. I am pretty sure there has to be more to
it.

Could I request an introduction section in the docs that would explain what
quaternions are and why one would want to use them?
