+VADERE is a simulation framework for pedestrian flow analysis. VADERE's core features:
+
+- CLI **and** an easy-to-use GUI interface.
+- Shipped with different locomotion models:
+  * Gradient Navigation Model (GNM)
+  * Optimal Steps Model (OSM)
+  * Social Force Model (SFM)
+  * Others: Behavioral Heuristics Model (BHM), ...

+## VADERE Implementation Using MVC Pattern
+
+**TODO:** Describe the general software structure according to MVC pattern.
+
+## VADERE's Core: The Simulation Loop
+
+Like many other simulators, VADERE consists of a simulation loop.
+
+```java
+double currentTime = 0;
+...
+while (simIsRunning) {
+    ...
+    model.update(currentTime);
+    currentTime++;
+    ...
+}
+```
+
+The simulation loop is implemented in class `Simulation`. In each simulation loop, the locomotion model is updated. The locomotion model searches for the next position of an agent (a simulated pedestrian). I.e., a locomotion model implements a well-defined interface `Model`. This concept makes VADERE a generic framework in which different locomotion models can be implemented easily.
