 # Quaternions
 
-The functions described in this chapter provide support for quaternions.
+The functions provided by this module add support for quaternions.
 The algorithms take care to avoid unnecessary intermediate underflows
 and overflows, allowing the functions to be evaluated over as much of
 the quaternion plane as possible.
-
-The quaternion types, functions and arithmetic operations are defined in
-the dir `vsl.quaternion`.
