-The line list simulation requires that we define a contact distribution,
-period of infectiousness, onset-to-hospitalisation delay, and
-onset-to-death delay. We can load these from the library of
-epidemiological parameters in the `{epiparameter}` R package if
-available, or if these are not in the database yet (such as the contact
-distribution for COVID-19) we can define them ourselves.
+A line list can be simulated by calling `sim_linelist()`. The function
+provides sensible defaults to quickly generate a epidemiologically valid
+data set.

+However, to simulate a more realistic line list using epidemiological
+parameters estimated for a infectious disease we can use previously
+estimated epidemiological parameters. These can be from the
+`{epiparameter}` R package if available, or if these are not in the
+`{epiparameter}` database yet (such as the contact distribution for
+COVID-19) we can define them ourselves. Here we define a contact
+distribution, period of infectiousness, onset-to-hospitalisation delay,
+and onset-to-death delay.
+
+``` r
+library(epiparameter)
+```
 
 ``` r
 # create COVID-19 contact distribution
