To make everything run correctly, you'll need to set the correct ID for the weather.
- Go to openweathermap.org
- Search for your town/city
- Copy the last 7 digits in the URL bar
- Replace
YOUR ID HERE
(line 88) inmain.js
with the 7 digit number you just copied
Then, you should be able to run it with no issues. If you encounter any issues, please make an issue/PR on github.
