+Welcome to i3,
+This message is simply intended to introduce you to the basics of i3 with it's default configuration.
+For further details have a look at the man page or the User's Guide which you can find at:
+http://i3.zekjur.net/docs/userguide.html
+
+
+Configuration Files
+/etc/i3/config is the default configuration
+~/.i3/config is your configuration, it's recommended to copy the default one to this file and modify it.
+
+
+Keybindings for the first steps
+The following explanation is related to the QWERTY layout, but as the default configuration uses
+keycodes instead of keysymbols for binding, they're still the same keys even with another layout.
+The Mod1 key is usually bound to the Alt key at your keyboard.
+
+Mod1+Enter opens a terminal which is by default urxvt
+
+Mod1+v starts dmenu
+
+The directional keys are by default j(left), k(down), l(up) and ;(right).
+
+Mod1+<directional key> moves the focus to the window in the given direction
+
+Mod1+Shift+<directional key> moves the window to the given direction, containers are created on the fly
+
+Mod1+<number> opens the corresponding workspace
+
+Mod1+Shift+<number> moves a window to the wished workspace
+
+Mod1+h sets the mode of a container to stacking
+
+Mod1+e sets the mode back to default
+
+Mod1+f sets a window to fullscreen and also back to default mode
+
+Mod1+Shift+Space sets a window into floating mode or back into tiling mode
+
+Mod1+Shift+q closes a window
+
+Mod1+Shift+r restarts i3
+
+Mod1+Shift+e exits i3
+
+
+For detailed information about the configuration file syntax, the keybindings which weren't mentioned
+here and other features take a look at the User's Guide and the man page.
