 Prerequisites: a compositor implementing the ivi_controller interface must
 be running and XDG_RUNTIME_DIR must be set so the wayland socket can be found.
 
+The configuration for the window manager (the layers.json file, as specified
+int the next section) needs to be available. The environment variable
+LAYERS_JSON=/path/to/layers.json needs to be set.
+
 To run from the build directory use:
 
-afb-daemon --ldpaths=$PWD/src
+env LAYERS_JSON=/path/to/layers.json afb-daemon --ldpaths=/path/to/winman-binding/
 
 
 
 JSON Configurations
 ---------- ----- -- - -
-ids.json: This file configures a mapping of surface id to some layer id. Also
-          In this configuration are information on the actual drawing rectangles
-          that applications need to use on a particular layer.
-layout.json: A layout spcification. It is as of yet mostly unused and if not
-             parsed correctly should not interfere with window manager operation.
+layers.json: Layers and layout description. In order for the window manager to
+             work, this file needs to be available and passed to the window manager
+             using the environment variable LAYERS_JSON. An *example* layers.json is
+             provided.
