 ## Description
 
-Reactor is a tool that lets you periodically execute tasks that depend on certain conditions.
+Rhynodge is a tool that lets you periodically execute tasks that depend on certain conditions.
 
 Its concept is quite similar to websites like ifttt (“if this then that”): you evaluate an input condition (e. g. data from a website, Facebook or Twitter posts, incoming emails, existence of a file), and if it evaluates to “yes” you execute a certain action.

-The core of Reactor comprises ``Reaction``s which in turn consist of ``Query``s, ``Filter``s, ``Trigger``s, and ``Action``s.

 The result of a ``Trigger`` is an ``Output``.
 
+### Watcher
+
+A watcher combines a query, a list of filters, and a trigger into a single unit which can be configured a lot easier than the separate components. For example, you could have a “Twitter” that finds new status updates for a username and that only needs to be configured with that username; the rest of the configuration is contained in the watcher.

+A ``Watcher`` does not do any processing but instead offers a ``Query``, a list of ``Filter``s, and a ``Trigger``.

 ### Action
 
 If a trigger found a change, the action is then executed. Again, an action can be almost anything: it can send an email, it can execute programs, print documents, initiate phone calls, take a picture from a webcam — anything you can program can be used an an action.
 
 ## Configuration
 
-Reactor’s configuration uses JSON files (I tried using XML first but apparently polymorphic deserialization is something that is not easily done with XML parsers). The format of a ``Chain`` configuration is pretty straight-forward and can be seen in the example configuration files.
