Configuration

A minimal configuration file "default.json" looks like this: 

{
  "appid": "<insert your openweathermap api key here>",
  "location": { "id": 2887186 }
}

First you might want to get an appid from openweathermap. You can find the id of your nearest location with some of the geo calls of the API: https://openweathermap.org/current#geo
