+dwl is a compact, hackable compositor for Wayland based on wlroots.
+It is intended to fill the same space in the Wayland world that dwm
+does in X11, primarily in terms of philosophy, and secondarily in terms
+of functionality. Like dwm, dwl is:
+
+•Easy to understand, hack on, and extend with patches
+•One C source file (or a very small number) configurable via config.h
+•Limited to 2000 SLOC to promote hackability
+•Tied to as few external dependencies as possible
+
+dwl is not meant to provide every feature under the sun.
+Instead, like dwm, it sticks to features which are
+necessary, simple, and straightforward to implement given the base on
+which it is built. Implemented default features are:
+
+•Any features provided by dwm/Xlib: simple window borders, tags,
+keybindings, client rules, mouse move/resize. Providing a
+built-in status bar is an exception to this goal, to avoid
+dependencies on font rendering and/or drawing libraries when an
+external bar could work well.
+•Configurable multi-monitor layout support, including position and
+rotation
+•Configurable HiDPI/multi-DPI support
+•Idle-inhibit protocol which lets applications such as mpv disable
+idle monitoring
+•Provide information to external status bars via stdout/stdin
+•Urgency hints via xdg-activate protocol
+•Support screen lockers via input-inhibitor protocol
+•Various Wayland protocols
+•XWayland support as provided by wlroots (can be enabled in config.mk)
+•Zero flickering - Wayland users naturally expect that
+"every frame is perfect"
+•Layer shell popups (used by Waybar)
+•Damage tracking provided by scenegraph API
+
+NOTE: the autostart patch is enabled by default, if you need a
+wallpaper modify the autostart patch file at line 23 and change
+"swaybg --image /xap/local/background", NULL, to
+"swaybg -i (your wallpaper path)", NULL,
+
+If you want to start dwl without a login manager just type dwl
+If you want to start dwl with somebar launch with: dwl -s somebar
+You can disable the autostart patch and use azote to have a wallpaper
+like this dwl -s ~/.azotebg
+
+Suggested programs:
+swaybg for background/wallpaper
+bemenu wayland menu
+fuzzel wayland menu
+rofi-lbonn-wayland
+alacritty terminal emulator
+foot terminal emulator
+
+OPTIONS:
+
+Use the Xwayland patch:
+
+  XWAYLAND=yes sh dwl.SlackBuild
+
+Use Windows key instead of alt:
+
+  MODWINKEY=yes sh dwl.SlackBuild
+
+Use fuzzel instead of bemenu:
+
+  FUZZEL=yes sh dwm.SlackBuild
+
+Use somebar (similar to dwm bar)
+
+  SOMEBAR=yes sh dwm.SlackBuild
+
