 Get the current weather for a given coordinate.
 
-```plaintext
+```
 open-meteo current-weather [OPTIONS] --latitude <LATITUDE> --longitude <LONGITUDE>
 ```
 
 #### Options
-
 - `-l, --latitude <LATITUDE>`: Latitude as a decimal number.
 - `-L, --longitude <LONGITUDE>`: Longitude as a decimal number.
+
+#### Flags
 - `-a, --all`: Prints all available parameters.
 - `-d, --is-day`: Prints if it is day or night.
 - `-t, --temperature`: Prints the decimal temperature.
 - `-w, --windspeed`: Prints the decimal wind speed.
 - `-W, --winddirection`: Prints the wind direction angle.
-- `-c, --clean`: Cleans the output and only shows the values separated by commas. The order of values is as follows: is_day, temperature, windspeed, winddirection. Example output: `1,22.4,12.5,170.0`.
+- `-c, --clean`: Cleans the output and only shows the values separated by commas.
+    - The order of values is as follows: is_day, temperature, windspeed, winddirection.
+
+#### Examples
+- Standard usage: `open-meteo-cli current-weather -l 5 -L 5 -a`
+
+```
+=== Current weather for Latitude: 5, Longitude: 5 ===
+Night
+Temperature: 28.4°C
