• This is our original codebase that we wrote in 2020 for a WhatsApp bot that provides COVID-19 statistics in Indonesia.
• You can check out the full changelog here: https://github.com/mramirid/whatsapp-bot-covid/commits/v1.
• We also published an article about this codebase in this journal: http://jifosi.upnjatim.ac.id/index.php/jifosi/article/view/101.
