 ### Encoding
 
-Field elements and scalars are encoded as 32 byte big-endian numbers. Curve points are encoded as two field elements `(x, y)`, where the point at infinity is encoded as `(0, 0)`.
+Field elements and scalars are encoded as 32 byte big-endian numbers. Curve points are encoded as two field elements `(x, y)` representing the affine coordinates, where the point at infinity is encoded as `(0, 0)`.
 
 Tuples of objects are encoded as their concatenation.
