-``` ./cayley repl --dbpath=testdata.nt ```
+```
+./cayley repl --dbpath=testdata.nt 
+```

+You should see a `cayley>` REPL prompt. Go ahead and give it a try:

+// Simple math
+cayley> 2 + 2

+// Javascript syntax
+cayley> x = 2 * 8
+cayley> x

+// See all the entities in this small follow graph.
+cayley> graph.Vertex().All()

+// See only dani.
+cayley> graph.Vertex("dani").All()
+
+// See who dani follows.
+cayley> graph.Vertex("dani").Out("follows").All()
