+This example uses the reqwest crate to make an HTTP request to the
+OpenWeatherAPI and the serde and serde_json crates to parse the JSON response.
+
+The WeatherResponse struct represents the top-level JSON object in the response,
+with fields for the main weather information and a list of weather conditions.
+The Main struct represents the main weather information, with fields for
+temperature, pressure, humidity, and minimum and maximum temperature. The
+Weather struct represents a single weather condition, with fields for the
+condition ID, main condition, description, and icon.
+
+The get_weather function makes a request to the OpenWeatherAPI for the given
+city and parses the response into a WeatherResponse struct. It then prints out
+the main weather information and the list of weather conditions.
+
+You'll need to replace API_KEY with your own API key, which you can get by
+signing up for a free account at https://home.openweathermap.org/users/sign_up.

+The last part of the response is snipped here again. I assume, that the number
+of token for my free account is reached here. We can probably work around that
+by requesting more concise parts of the code.
+
+** I dont want to use the 'city' parameter
+
+#+begin_quote
+can I use lat,lon coordinates instead of the city parameter?
+#+end_quote
+
+Response:
+
+#+begin_quote
+Yes, you can use latitude and longitude coordinates instead of the city
+parameter to get the weather information for a specific location from the
+OpenWeatherAPI.
+
+To do this, you'll need to modify the API request URL to include the lat and lon parameters. For example:
+#+end_quote
+
+#+begin_src rust
+  let url = format!(
+    "https://api.openweathermap.org/data/2.5/weather?lat={lat}&lon={lon}&appid={API_KEY}",
+    lat=lat, lon=lon, API_KEY=API_KEY
+);
+
+#+end_src
+
+#+begin_quote
+Here, lat and lon are the latitude and longitude coordinates of the location you
+want to get the weather information for. Make sure to replace API_KEY with your
+own API key, which you can get by signing up for a free account at
+https://home.openweathermap.org/users/sign_up.
+
+You can then use the modified URL to make the API request and parse the response
+as shown in the previous example.
+#+end_quote
+
+I like how it refers to the previous output and tells me which part to update.
