 ## Detail of plugins
 
+
+ ### Hello World
+
+A sample Hello World plugin for demonstration and learning purposes.
+
+This plugin provides a few unauthenticated requests, all beginning with "ping" ("_pingSample_", "_pingJson_", "_pingFail_"...) to demonstrate basic binder capabilities.
+
+
+ ### Authentication
+
+An sample Authentication plugin for demonstration purposes.
+
+This plugin 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.
+
+
+ ### Tic Tac Toe
+
+A sample Tic Tac Toe game plugin.
+
+This plugin provides an interactive Tic Tac Toe game where the binder returns the grid as a JSON response. 
+
+
  ### Audio
 
 A sample Audio plugin with 2 backends:
  * ALSA (mandatory)
  * PulseAudio (optional)
 
+This plugin is able to initialize a specific soundcard, define volume levels, channels (mono/stereo...), mute sound, and play a 22,050 Hz PCM stream.
+
 _(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 plugin 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**)_
