-### LXQt application switcher.
-This is a simple application to switch between applications in lxqt. Have lxqt integration, including theming.
-For example ambiance theme it looks like this:
+# LXQt application switcher
+
+## Overview
+
+LXQt application switcher is an application switcher, hence a tool to change the active window by cycling
+through the available ones, geared towards the [LXQt desktop environment](http://lxqt.org).
-After installation, to configure this switcher you just go to lxqt-settings/Session Settings and enable this:
+It integrates with LXQt including theming and is meant to be more configurable and featureful than e. g.
+its counterpart provided by Openbox.
+(For now theme Ambiance only is supported. Other themes can still be used but make LXQt application
+switcher fall back to a default theme.)
+
+## Installation
+
+LXQt component [lxqt-globalkeys](https://github.com/lxde/lxqt-globalkeys) is the only mandatory build- and
+runtime dependency as it's needed itself and pulls all other needed dependencies including Qt as well.
+
+LXQt application switcher is relying on CMake and can hence be installed by running `cmake`, `make` and
+`make install`, optionally from a dedicated build directory.
+A CMake option like `-DCMAKE_INSTALL_PREFIX=/usr` will be needed most of the time to have the program installed
+at paths commonly used these days.
+
+In Arch Linux the tool can be installed via [AUR](https://aur.archlinux.org/) package
+[lxqt-appswitcher-git](https://aur.archlinux.org/packages/lxqt-appswitcher-git/).
+
+## Configuration
+
+### Keyboard shortcuts
+
+LXQt application switcher is using the shortcuts defined by lxqt-globalkeys.
+These are configured in dialogue "Global Actions Manager" (binary `lxqt-config-globalkeyshortcuts`) - topics
+"[reverse] switch applications" in column "Description". Default settings are `Alt+Tab` and `Alt+Shift+Tab` to
+cycle in regular and reverse order respectively.
+
+It must be ensured that these shortcuts aren't used by the window manager. (Technically it's possible to assign
+different shortcuts to LXQt application switcher and e. g. an application switcher of a window manager and hence
+use the two in parallel. This will hardly ever make sense, though.)
+In **Openbox** [actions](http://openbox.org/wiki/Help:Actions) `NextWindow` and/or `PreviousWindow` have to be
+detached from the keyboard [bindings](http://openbox.org/wiki/Help:Bindings). This is best done by uncommenting or
+removing the corresponding sections in `~/.config/openbox/rc.xml`. If the file is missing `/etc/xdg/openbox/rc.xml`
+can be copied and used as template, the sections themselves will look like
+```
+
+
+[...]
+
+```
+and
+```
+
+
+[...]
+
+```
+For changes to take effect either start a new session or run `openbox --reconfigure`.
+In **KWin** the shortcuts can be handled from KDE's "System Settings" (binary `systemsettings[5]`) under Workspace -
+Window Management - Task Switcher, using **Xfwm4** in dialogue "Window Manager" (binary `xfwm4-settings`), both
+times changes take effect at once.
+
+### Auto start
+
+The application itself is run as so-called LXQt Module. As such it has to be enabled from dialogue
+"LXQt Session Settings" (binary `lxqt-config-session`).
-And in lxqt-settings/Application switcher setup switcher as you wish.
+### Settings
-In openbox, you must disable default application switcher. You can do it in ~/.config/openbox/rc.xml and comment section
-```

+The actual configuration can be tweaked by dialogue "Application switcher" which can be found in LXQt's main panel
+menu as well as in the "LXQt Configuration Center".
