 The most relevant part is the `providers` section. Here, we define a `CSV Provider`,
 pointing the file path to the `/data` directory we will mount (see next) from the local
 directory into the Docker container above. Because a CSV is not a spatial file, we explicitly
 configure pygeoapi so that the longitude and latitude (x and y) is mapped from the columns `lon`
-and `lat` in the CSV file.
+and `lat` in the CSV file. Notice the `storage_crs` parameter, which indicates the coordinate system which is used in the source data.
