   # Group Observation
   
  -## Retrieve weather observation [/observation?location={latitudeInDegree,longitudeInDegree}{&speedUnit}{&temperatureUnit}{&precipitationUnit}]
  +## Retrieve weather observation [/observation?locatedAt={locatedAt}&fields={fields}&]
   
   #### Example
   `https://api.weather.mg/observation?location=53,13`
   
   ### Observed weather for a given *latitude* and *longitude* [GET]
   
  -This resource provides data from existing weather observation stations. These are the latest values/parameters they provide.
  +This resource provides data from existing weather observation stations.
  +These are the latest values/parameters they provide.
   For any requested location a relevant station is computed.
  -For the relevance the stations distance, height difference and available parameters are taken into concern.
