+
+!!! note
+    The functions described in this section are experimental. While the overall
+    functionality provided will stay the same, names of specific functions or
+    conventions for the return values might change in future versions.
+
+This section describes the functionality for finite-dimensional associative
+algebras (or just *algebras* for short). Since different applications have different requirements, 
+the following types of algebras are implemented:
+- structure constant algebras,
+- matrix algebras,
+- group algebras,
+- quaternion algebras.
+
+These share a common interface encompassing a wide range of functions, which is
+indicated by the use of the type `AbstractAssociativeAlgebra` in the signature.
