+## Scope
+
+`ordersim` focuses on execution replay and execution-aware simulation. Areas of
+interest include order-book replay, market replay, latency modeling,
+queue-position effects, fill simulation, execution modeling, execution-aware
+backtesting, and market microstructure research.
+
 ## What It Does
 
 - Replays order-book data and simulates order execution with explicit order
