+Settings for post-processing are read from an input file, by default
+`post_processing_input.toml` (you can select a different one using the
+`setup_input_file` argument to `get_run_info()`). The relevant settings for
+interactive use are the default indices (`iz0`, `ivpa0`, etc.) that are used to
+select slices for 1D/2D plots and animations. The settings are read by
+`setup_makie_post_processing!()` which is called by default as part of
+`get_run_info()`. You might want to call it directly if you load both 'moments'
+and 'distribution functions' data, to get sensible settings for both at the
+same time.
 
 Then you can make 1d or 2d plots, e.g.
