 ### Optional Configuration
 
 ```elixir
-# When a binary is passed to `Geo.PostGIS.Geometry.cast/1` implementation of `Ecto.Type.cast/1`, it is assumed to be a GeoJSON string. When this happens, geo_postgis will use Poison, by default, to convert the binary to a map and then convert that map to one of the Geo structs. If in these cases you would like to use a different JSON parser, you can set the config below.
