 ### Installation
-Add the folder containing gramm.m to your path
+Add the folder containing the @gramm class folder to your path
 ### Compatibility
 Tested under Matlab 2014b+ versions. With pre-2014b versions, gramm forces <code>'painters'</code>, renderer to avoid some graphic bugs, which deactivates transparencies (use non-transparent geoms, for example <code>stat_summary('geom','lines')</code>). The statistics toolbox is required for some methods: <code>stat_glm()</code>, some <code>stat_summary()</code> methods, <code>stat_density()</code>. The curve fitting toolbox is required for <code>stat_fit()</code/>.

 ### Superimposition of gramm objects on the same axes
 By making calling the update() method after a first draw, the same axes can be reused for another gramm plot.
 Here this allows to use different groupings for the points and for the glm fit.
