 Installation
 ============
 
-gedit requires GTK+ >= 3.16, GtkSourceView >= 3.17.3 and
+gedit requires GTK+ >= 3.19.0, GtkSourceView >= 3.18 and
 libpeas >= 1.14.1 libraries. It also has a run-time dependency on an
 icon theme for its icons. If gedit fails to display icons, installing
 GNOME's default adwaita-icon-theme is a simple way of providing them.
