# Emacs X Window Manager
EXWM (Emacs X Window Manager) is a full-featured tiling X window manager for
Emacs built on top of [XELB](https://github.com/ch11ng/xelb).
EXWM (Emacs X Window Manager) is a full-featured tiling X window manager
for Emacs built on top of [XELB](https://github.com/ch11ng/xelb).
It features:
+ Fully keyboard-driven operations
+ Hybrid layout modes (tiling & stacking)
+ Workspace support
+ Dynamic workspace support
+ ICCCM/EWMH compliance
+ (Optional) RandR (multi-monitor) support
+ (Optional) system tray
+ (Optional) Built-in system tray
Please check the [User Guide](https://github.com/ch11ng/exwm/wiki)
for more details.
Please check out the
[screenshots](https://github.com/ch11ng/exwm/wiki/Screenshots)
to get an overview of what EXWM is capable of,
and the [user guide](https://github.com/ch11ng/exwm/wiki)
for a detailed explanation of its usage.
**Note**: If you install EXWM from source, you need to manually install XELB
(either from source or GNU ELPA).
**Note**: If you install EXWM from source, it's recommended to install
XELB also from source (otherwise install both from GNU ELPA).
