+# Introductory Explanation for Carry-less and Gallois Field
+
+There are three completely separate types of Galois Field
+arithmetic which are not well explained even in introductory
+literature.
+
+* GF(2) which is covered by bibary XOR
 
 # Instructions for Carry-less Operations aka. Polynomials with coefficients in `GF(2)`
