The application uses http://fontawesome.io/, which needs to be downloaded into www/fonts/ directory.

Go to http(s)://<example.com>/update.php

Note: If the changes are not reflected on the website, go to the source Google Sheet and Stop publishing it (File->Publish to the web...->Stop publishing) and Start publishing it again (explanation: it seems that Google Sheets sometimes do not reflect the changes made online into its downloadable versions)

Note: www/inc/*.py files are rather tightly connected to the current dataset. They allow to add more chambers in the dataset, but not to change questions (structure of columns)

Go to http(s)://<example.com>/clear-cache.php

Note: The cache is also cleared during data update and regularly based on value in www/settings.json

Correct dataset needs to be set in www/inc/*.py files, as well as in www/settings.json
