 ## Usage
 
-The `apophis.jl` file in the `pha` directory contains an example script. This
-script may be called as:
+The `pha` directory contains the `apophis.jl` script which performs an
+orbit determination for asteroid (99942) Apophis from optical and radar astrometry. In order
+to run this script, the environment corresponding to the `Project.toml` contained in the
+`pha` directory has to be active and instantiated. This can be done, for example, by running
+the following command from the `pha` directory:
+
+``julia -e `import Pkg; Pkg.activate(); Pkg.instantiate()` # run this from the `pha` directory ``
+
+Once the `pha` environment is active, this script may be called from the `pha` directory
+with the default settings as:
+
+`julia --project apophis.jl`

+The `--help` option can be passed to see a list of the customizable settings
