+leinwand - a new DRM-based window system
+----------------------------------------
+leinwand is a new DRM-based window system in order to replace the obsolete X
+Window System and to provide a modern and frugal window system on DRM-capable
+Unices, such as Linux.
+
+
+Requirements
+------------
+In order to build leinwand you need the DRM header files (usually part of the
+linux kernel header files).
+
+
+Installation
+------------
+Edit config.mk to match your local setup (leinwand is installed into
+the /usr/local namespace by default).
+
+Afterwards enter the following command to build and install leinwand
+(if necessary as root):
+
+    make clean install
+
+
+Running leinwand
+----------------
+Make sure you have setup DRM in your kernel settings being usable and make sure
+that you have a proper mode setup for the given screens you drive with DRM.
+Details on these vary on different platforms and we will extend the manual
+accordingly in the future.
+
+There is also a legacy leinwand port on top of X11, which we only recommend for
+trying.
