 | In doing these exercises you might find it helpful to use the `macpan2` [website](https://canmod.github.io/macpan2) as a reference. Pages that could be particularly useful are the [quick start guide](https://canmod.github.io/macpan2/articles/quickstart) and documentation for the [`mp_tmb_model_spec`](https://canmod.github.io/macpan2/reference/mp_tmb_model_spec), [`mp_per_capita_flow`](https://canmod.github.io/macpan2/reference/mp_per_capita_flow), [`mp_simulator`](https://canmod.github.io/macpan2/reference/mp_simulator), and [`mp_trajectory`](https://canmod.github.io/macpan2/reference/mp_trajectory). |
