+# Start level example (start_level.json)
+
+This example demonstrates the use of the `start_level` parameter of the capacity
+feature.
+
+Find some notes about the example below:
+
+- All stops have a `-1` quantity (all pickups), hence, the vehicles can service
+  as many as they have capacity but no more.
+- The first vehicle `v1` defines a start level of 0 and can therefore service
+  as many stops as it has capacity.
+- The second vehicle `v2` defines a start level equal to its capacity and can
+  therefore service no stops at all.
