+### wxWidgets version
+
+By default, Slic3r PE looks for wxWidgets 3.1, this is because the 3.1 version has
+a number of bugfixes and improvements not found in 3.0. However, it can also be built with wxWidgets 3.0.
+This is done by passing this option to CMake:
+
+    -DSLIC3R_WX_STABLE=1

 By default Scli3r builds the release variant.
