 ### SingleQuery function
 
 The SingleQuery function is designed to make a single request against the API.
 
 Arguments:
-- query - This is a Golang struct which when passed to the function will be reformatted into a proper query to be executed against the IP-API API.
-- apiKey - This is for when you are using the pro version of IP-API and which to have the [increased functionality](https://members.ip-api.com/).
-- baseURL - This is really only intended to be used if you are going through some sort of IP-API proxy. Otherwise, this can be left blank, and the URL will be determined by whether an API Key is provided or not.
+
+- query - This is a Golang struct which when passed to the function will be reformatted into a proper query to be
+  executed against the IP-API API.
+- apiKey - This is for when you are using the pro version of IP-API and which to have
+  the [increased functionality](https://members.ip-api.com/).
+- baseURL - This is really only intended to be used if you are going through some sort of IP-API proxy. Otherwise, this
+  can be left blank, and the URL will be determined by whether an API Key is provided or not.
 
 Returns:
+
 - Location - Golang struct that contains the results of the query.
 - error - Any errors.
 
 ### BatchQuery function
 
-The BatchQuery function is designed to take advantage of IP-API's [batch](http://ip-api.com/docs/api:batch) API. This is designed to allow for multiple queries to be executed at the same time to reduce overall query time.

 Returns:

 - error - Any errors.

 ### ValidateFields function
 
 The ValidateFields function is designed to validate that the fields which are being passed to the IP-API are valid.
 
 Arguments:
-- fields - This is a string which contains comma separated values of the fields. It will be checked against the AllowedAPIFields.
+
+- fields - This is a string which contains comma separated values of the fields. It will be checked against the
+  AllowedAPIFields.
 
 Returns:
-- string - The same string which was passed to it in the fields argument.
+
+- string - The same string which was passed to it in the fields' argument.
 - error - Any errors.
 
 ### ValidateLang function
 
 The validateLang function is designed to validate the lang string which is one of the languages supported by IP-API.
 
 Arguments:
+
 - lang - the string which contains the desired language.
 
 Returns:
+
 - string - The same string which was passed to it in the lang argument.
 - error - Any errors.
