 @ChapterTitle Constructing One-Sided Quasigroups, Racks, and Quandles.
+@Section from_scratch
+@SectionTitle Direct constructors
+  All of the functions in this section produce magmas (of one of the
+  categories with which &RAQ; is concerned) from data of other (non-domain)
+  types.

 @Chapter basic
 @ChapterTitle Basic Notions
+   In order to build up and define one-sided quasigroups, racks, and
+   quandles, &RAQ; must define several lower-level objects and properties,
+   which are documented in this section. Although logically they come before
+   the domain constructors and operations, they are presented afterwards
+   because it's rare that one needs to use them directly when working with
+   &RAQ;.

 @Chapter technical
+  This chapter covers computational/operational aspects of &RAQ;
+  rather than mathematical ones.
