-The letterswitharrows package does provides LaTeX math-mode commands for setting left and right arrows over mathematical symbols, so that the arrows dynamically scale with the symbols.
+The letterswitharrows package provides LaTeX math-mode commands for setting left and right arrows over mathematical symbols, so that the arrows dynamically scale with the symbols.
 While it is possible to set arrows over longer strings of symbols, the focus lies on single characters.

+% \DescribeOption{linewidth}
+% Specifying \verb|linewidth=<value>| as a package option allows you to adjust the line width of the arrows to adjust for the weigth of the maths font you are using.
+% The default value is \verb|linewidth=0.3|.
+
+
 % \DescribeOption{tweaks}
 % Specifying the \verb|tweaks| option applies per-letter scaling adjustments to some of the single-letter shorthands. This is enabled by default.
 % These are specific to Latin Modern Math and subject to be changed on a whim. If you wish a more stable behaviour specify \verb|tweaks=false|.
