 # Overview
-`execlog` is a lightweight multi-threaded job framework
+`execlog` is a lightweight multi-threaded job framework written in Python. It implements a
+simple event-based model over core Python utilities like `ThreadPoolExecutor` to
+facilitate reactivity and manage concurrent responses.
 
-- **Handler**: live-reload handshake manager for connecting pages
-- **Listener**: 
-- **Router**
-- **Server**: 
+There are a few top-level classes exposed by the package:
+
+- **Router**: Central event routing object. Routers facilitate route registration,
+  allowing for _pattern_-based matching of _events_ to arbitrary _callback_ functions. For
+  example, you could have a function that converts a PDF file to a collection images
+  (_callback_), and want this function to be called for a new files (_event_) that match
+  the glob `*.pdf` (_pattern_).
+- **Listener**: Connective event listening object, often created directly by router
+  instances. Listeners pay attention to events arising along registered routes of an
+  affiliated router, passing them through (after optional delays, debouncing, filtering,
+  etc). In the above example, the associated `Listener` instance might wrap a tool like
+  iNotify to dynamically respond to file events.
+- **Server**: Long-running process manager for listeners and optional live-reloading via
+  HTTP. Interfaces with listener `start()` and `shutdown()` for graceful interruption.
