+The files of the `l3kernel` bundle provide an API for TeX programmers
+with defined syntax conventions, completely separating it from document level
 syntax. Hence, the commands provided are not intended for use at the document
 level nor for use in describing design layouts in document class files.
 
-This API provides the foundation on which the LaTeX3 kernel and other advanced
-extensions are built. Special care has been taken so that they can be used
-within a LaTeX2e context as regular packages.
