+Version
+*******
+
+| You can also try a specific version of bowelyzer, by downloading it from the |bowelyzer-git-repository| (version tar balls are listed under the **Tag** header).
+| Extract the tar ball into the above mentioned **Extensions/local** folder on your specific operating system.

Usage
_____
-Go to the cloned directory and open **bowelyzer.scd** in your favorite SuperCollider IDE.
-All further steps are explained there.
+| Go to the cloned directory and open **bowelyzer.scd** in your favorite SuperCollider IDE.
+| How to start the application with and without configuration is explained there.
+
+Configuration
+*************
+| Bowelyzer is configured by a |json| file with pre-defined fields.
+| Have a look at the shipped example, to see how it works and what is available.
+| Generally there are some global options (such as *addresses* and *ports*) and per channel configurations (such as *inputs* and *controls*).
+
+* **Note**: The available inputs of |supercollider| are defined by your |supercollider_startupfile|. Make sure to set the correct amount of |supercollider_numinputbuschannels|.
+Output
+******
+Bowelyzer sends |osc| messages to a preconfigured host and port of the form
+**[/name, amplitude, pitch, hasPitch, onSet]**, where **/name** refers to the
+name of the channel, **amplitude** to the detected amplitude (0.0 - 1.0), **pitch** to
+the detected frequency (20Hz - 20kHz), **hasPitch** (0, 1) to whether a pitch was
+detected and **onSet** (0, 1) to whether an onset was detected.
