Specifically, we wanted to allow user input for these decisions:
**1.** Inform the user that the programme will download the CSV and KML files and **ask them for permission to store the files locally**.
**1.** Allow the user to **accept the default directory or set a new one.**
<details><summary> See the Code</summary>
```java

String answer;
// welcome and information for user

+ "2: convert it into a KML structure\n"
+ "3: download a tweets.csv file from the web\n"
+ "4: convert it into a KML structure\n"
+ "5: launch both kml files in Google Earth\n\n"
+ "The downloaded files will be stored at C:\\Users\\Public\\Documents\n"
+ "If this is fine, please enter Y below and hit enter to continue! If not, we will stop the programme and you can manually change the directory at the very top of this class's code.");

**3.** Ask the user if they would like to **proceed to launch** Google Earth.
**3.** Ask the user if they would like to **proceed to launch** Google Earth. This step also made sure that the programme would halt again (giving the user some time to actually read the console output before Google Earth launches). If the users does not answer with some form of "yes", the programme will end with a friendly good-bye message.
