-### Manual Stepping Interface
-
-A new feature in QuTiP v5 is that time steps can be controlled manually.
-This is specifically useful if the Hamiltonian depends on an external control parameter such as a field strength.
-Such parameters can be updated in each step using the optional parameter `args`.
-In practice, this can look like this:
-
-```python
-t = 0
-dt = 40 / 100
-se_solver2 = SESolver(H)
-se_solver2.start(psi0, t)
-while t < 40:
-    t = t + dt
-    psi = se_solver2.step(t)
-    # process the result psi and calculate next time step
-```
-
 ### Solver and Integrator Options
 
 Another change in QuTiP v5 is that the `options` argument takes a standard Python dictionary.
