## Presentation
This extension has been written by F. Pantigny (`fpantigny@wanadoo.fr`).
-The extension `witharrows` gives a LaTeX environment `{WithArrows}` which is similar
-to the environment `{aligned}` of `amsmath` but which gives the possibility to draw arrows
-on the right side of the equations for explanations.
+
+The LaTeX package `witharrows` provides environments `{WithArrows}` and `{DispWithArrows}`
+similar to the environments `{aligned}` and `{align}` of `amsmath` but with the possibility to draw arrows on the right side of the alignment. These arrows are usually used to give explanations concerning the mathematical calculus presented.
