+Transmitter plugin
+
+The current implementation of Transmitter is a stub which interfaces to
+other Weston parts appropriately, but all networking is just a mockup.
+
+Sections in this file describe:
+- How to build
+- How to write weston.ini
+- How to test
+
+How to build
+============
+Configure Weston with --enable-surface-remoting to build the Transmitter
+plugin.
+
+How to write weston.ini
+=======================
+To load transmitter plugin to weston, add 'transmitter.so' to the 'modules'
+key under '[core]', and make sure the 'shell' is 'ivi-shell.so'.
+
+The destination of remoting is configured in weston.ini.
+Add output name, server address, port number, output's width and height key
+under '[remote-output]'.
+You can speficy multiple [remote-output].
+
+In details, see 'weston.ini.transmitter'.
+
+How to test
+===========
+You can use server side test application in waltham-server directory.
+
+If you set 'WALTHAM_DEBUG=1' to your environment valuable, you can
+see the log like this:
