+ExOwm utilizes some cool features such as:
 
 *   concurrent API calls
 *   super fast generational caching
 *   access to **main** [OWM APIs](http://openweathermap.org/api)!
 
-It means that each location entry passed within the list spawns separate task (Elixir worker process) which is checking whether the request has been already sent within a time interval, if yes, it's fetching the result from cache. Otherwise it sends API query, saves the result in cache and returns the data.
+Each location entry in the list spawns a separate task (Elixir worker process) to check whether the request has been made within a specified time interval. If it has, the result is fetched from the cache. Otherwise, an API query is sent, the result is cached, and the data is returned.
 
 ## To do
 
-*   Add Historical Data API
+*   Add remaining OWM APIs (including One Call API 3.0)
