The `from_bytes` example code looks fine to me, except that I'd probably use `enumerate` in the iteration;  i.e.,

    sum(b << 8*i for i, b in enumerate(little_ordered))

instead of

    sum(little_ordered[i] << i*8 for i in range(len(little_ordered)))

Also, in:

   if signed and little_ordered and (little_ordered[-1] & 0x80):

I wondered why you needed the `little_ordered` check.  But I see that `int.from_bytes(b'', 'little', signed=True)` produces `0`, which is a little bit disappointing:  I was expecting an exception.  (A signed format should have a sign bit, which is impossible if the length of the byte string is 0.)

The `to_bytes` example code is missing range checks for the input.  It may be clearer to simply state that in the docs, instead of modifying the example code to add the range checks.
