+# Simple Browser
+
+This is a little browser which depends on the QtWebEngine.
+
+In Contrast to the GtkWebkit the QtWebEngine runs under Chromium and
+is lighter and faster and supports more modern websites.
+
+Because of the fact that the Qt library is only provided for C++
+this browser is written in c++.
+
+## Keybindings
+
+- k : scroll up
+- j : scroll down
+- o : open url
+
+## TODO
+
+- Execute Shell Commands
+- add config-header-file
