-For \LaTeX3 programmers, the \pkg{fontscale} package provides some public \pkg{expl3} variables.
-No public \pkg{expl3} functions are provided.
+This section is relevant to \LaTeX3 programmers.
+
+The user commands \cs{SetFontStep}, \cs{SetFontScale}, \cs{SetFontSize}, \cs{ScaleFont}, and \cs{SetFontSizeBaselineskip} are set up to work with \cs{text_purify:n}.
+\cs{text_purify:n} will correctly remove these commands and their arguments.
+This includes the starred versions \cs{SetFontStep*}, \cs{SetFontScale*}, and \cs{SetFontSize*}.

+This package does not provide any public \pkg{expl3} functions.
+
+This package provides some public \pkg{expl3} variables.
The package stores in public variables the step, scale, size, and baselineskip of each font size command.
These variables should not be modified directly.
Instead, they should be modified only indirectly via the command \cs{fontscalesetup}.
