+## Realities
+
+It's impossible to create a system that can detect all bots. Well-behaving bots
+identify themselves in a consistent manner, usually via the User-Agent patterns
+this project provides. It is straightforward to identify these well-behaving
+bots, but misbehaving bots pretend to be real clients and use various mechanisms
+to evade detection.
