 * BDD-based methods
 * SMT-based methods
 
+## Example
+
+The `examples` directory contains sample input files.
+
+To quickly the BDD module you can perform verification of the TGC controller consiting of three trains:
+
+```
+$ ./reactics bdd -c f1 examples/bdd/tgc.rs
+```
+
+The above command tests the formula labelled `f1` in the input file.
+
+To test the SMT module you can perform reachability verification of the scalable chain system:
+
+```
+$ ./reactics smt examples/smt/chain_reaction.py 2 3 1
+```
