+Overview of bindings shipped with AFB-Daemon
+===========================================
+
+List of bindings
+---------------
+
+Here are the bindings shipped in the source tree:
+
+* Hello World
+* Authentication
+* Tic Tac Toe
+* Audio _(2 backends: ALSA/PulseAudio)_
+* Radio _(1 backend: RTLSDR RTL2832U)_
+* Media _(1 backend: Rygel UPnP)_
+
+All bindings may not be built, depending on the development libraries present on
+the system at build time.
+
+
+Detail of bindings
+-----------------
+
+### Hello World
+
+A sample Hello World binding for demonstration and learning purposes.
+
+This binding provides a few unauthenticated requests, all beginning with
+"ping", to demonstrate basic binder capabilities.
+
+**Verbs**:
+
+* _ping:_ returns a success response
+* _pingfail:_ returns a failure response
+* _pingnull:_ returns a success response, with an empty JSON response field
+* _pingbug:_ does a memory violation (intercepted by the binder)
+* _pingJson:_ returns a success response, with a complex JSON response field
+* _pingevent:_ broadcasts a global event
+
+<br />
+
+
+### Authentication
+
+A sample Authentication binding for demonstration purposes.
+
+This binding provides a few requests to demonstrate the binder's token-based
+security mechanism.
+
+Calling "_connect_" with a security token will initiate a session, calling
+"_refresh_" will issue a new token and invalidate the previous one, calling
+"_logout_" will invalidate all tokens and close the session.
+
+**Verbs**:
+
+* _ping:_ returns a success response
+* _connect:_ creates a session and returns a new token
+* _refresh:_ returns a new token
+* _check:_ verifies the passed token is valid
+* _logout:_ closes the session
+
+<br />
+
+
+### Tic Tac Toe
+
+A sample Tic Tac Toe game binding.
+
+This binding provides an interactive Tic Tac Toe game where the binder returns
+the grid as a JSON response. 
+
+**Verbs**:
+
+* _new:_ starts a new game
+* _play:_ asks the server to play
+* _move:_ gives a client move
+* _board:_ gets the current board state, as a JSON structure
+* _level_: sets the server level
+* _join_: joins an existing board
+* _undo_: undo the last move
+* _wait_: wait for a move
+
+<br />
+
+
+### Audio
+
+A sample Audio binding with 2 backends:
+
+* ALSA (mandatory)
+* PulseAudio (optional)
+
+This binding is able to initialize a specific soundcard, define volume levels,
+channels (mono/stereo...), mute sound, and play a 22,050 Hz PCM stream.
+
+**Verbs**:
+
+* _ping:_ returns a success response
+* _init:_ initializes backend, on the "default" sound card
+* _volume:_ gets or sets volume, in % (0-100)
+* _channels:_ gets or sets channels count (1-8)
+* _mute:_ gets or sets the mute status (on-off)
+* _play_: gets or sets the playing status (on-off)
+
+_(if PulseAudio development libraries are not found at build time, only ALSA
+will be available)_
+
+_(if a PulseAudio server is not found at runtime, the binding will dynamically
+fall back to ALSA)_
+
+_(a specifc backend can be forced by using this syntax before running afb-daemon
+: **$ export AFB_AUDIO_OUTPUT=Alsa**)_
+
+<br />
+
+
+### Radio
+
+A sample AM/FM Radio binding with 1 backend:
+
+* RTLSDR - Realtek RTL2832U dongles (mandatory)
+
+This binding is able to initialize specific RTL2832U dongles, switch between
+AM/FM modes, define frequency, mute sound, and play sound (if combining with
+the **audio** binding).
+
+**Verbs**:
+
+* _ping:_ returns a success response
+* _init:_ initializes backend, looking for plugged-in devices
+* _power:_ sets device power status (on-off)
+* _mode:_ sets device reception mode (AM-FM)
+* _freq:_ sets device frequency (in Hz)
+* _mute_: sets device mute status (on-off)
+* _play_: sets device playing status (on-off)
+
+_(if rtlsdr development libraries are not found at build time, this binding will
+not be built)_
+
+<br />
+
+### Media
+
+A sample Media Server binding with 1 backend:
+
+ * Rygel
+
+This binding is able to detect a local Rygel UPnP media server, list audio
+files, select an audio file for playback, play/pause/seek in this file, upload
+an audio file to the server.
+
+**Verbs**:
+
+* _ping:_ returns a success response
+* _init:_ initializes backend, looking for an active local UPnP server
+* _list:_ returns list of audio files, as a JSON structure
+* _select:_ select an audio files, by index number (001-...)
+* _play:_ plays the currently selected audio file
+* _stop:_ stops the currently selected audio file
+* _pause:_ pauses the currently selected audio file
+* _seek:_ seeks in the currently selected audio file, in seconds
+* _upload:_ uploads an audio file, with a POST request
+
+_(if GUPnP/GSSDP development libraries are not found at build time, this binding
+will not be built)_
+
