 ### Usage
 
-...
+For the dynamic task allocation, run:
+```python
+import gcaa
+gcaa.optimal_control_dta(
+    nt=4, # number of tasks
+    na=5, # number of agents
+    uniform_agents=False, # whether agents have an initial speed
+    n_rounds=100, # number of simulation rounds (precision vs compute time)
+    limited_communication=True, # whether communication is limited (True, False, or 'both')
+)
+```
+
+The sensitivity analysis of the parameters isn't available in Python.
