 \- `station_id` | Yes | ID | Identifier of a station. See [station_information.json](#station_informationjson).
 \-&nbsp;`num_vehicles_available` | Yes | Non-negative integer | Number of functional vehicles physically at the station that may be offered for rental. To know if the vehicles are available for rental, see `is_renting`. <br/><br/>If `is_renting` = `true` this is the number of vehicles that are currently available for rent. If `is_renting` =`false` this is the number of vehicles that would be available for rent if the station were set to allow rentals.
 \- `vehicle_types_available` <br/>*(added in v2.1)* | Conditionally REQUIRED | Array | REQUIRED if the [vehicle_types.json](#vehicle_typesjson) file has been defined. This field's value is an array of objects. Each of these objects is used to model the total number of each defined vehicle type available at a station. The total number of vehicles from each of these objects SHOULD add up to match the value specified in the `num_vehicles_available`  field.
-&emsp;\- `vehicle_type_id` <br/>*(added in v2.1)* | Yes | ID | The `vehicle_type_id` of each vehicle type at the station as described in [vehicle_types.json](#vehicle_typesjson). A vehicle type not available at the station can be omitted from the list or specified with a count=0.
+&emsp;\- `vehicle_type_id` <br/>*(added in v2.1)* | Yes | ID | The `vehicle_type_id` of each vehicle type at the station as described in [vehicle_types.json](#vehicle_typesjson). A vehicle type not available at the station can be omitted from the list or specified with `count` = `0`.
 &emsp;\- `count` <br/>*(added in v2.1)* | Yes | Non-negative integer | A number representing the total number of available vehicles of the corresponding `vehicle_type_id` as defined in [vehicle_types.json](#vehicle_typesjson) at the station.
 \-&nbsp;`num_vehicles_disabled` | OPTIONAL | Non-negative integer | Number of disabled vehicles of any type at the station. Vendors who do not want to publicize the number of disabled vehicles or docks in their system can opt to omit station `capacity` (in [station_information.json](#station_informationjson), `num_vehicles_disabled`, and `num_docks_disabled` *(as of v2.0)*. If station `capacity` is published, then broken docks/vehicles can be inferred (though not specifically whether the decreased capacity is a broken vehicle or dock).
 \-&nbsp;`num_docks_available` | Conditionally REQUIRED <br/>*(as of v2.0)* | Non-negative integer | REQUIRED except for stations that have unlimited docking capacity (e.g. virtual stations) *(as of v2.0)*. Number of functional docks physically at the station that are able to accept vehicles for return. To know if the docks are accepting vehicle returns, see `is_returning`. <br /><br/> If `is_returning` = `true` this is the number of docks that are currently available to accept vehicle returns. If `is_returning` = `false` this is the number of docks that would be available if the station were set to allow returns.
