1. Login to your terminal/SSH. If you do not know how - you can follow the guide here
2. Navigate to the root directory of your WordPress installation by using the following command:

cd public_html

3. Verify that you're in the correct directory by checking for the presence of the wp-config.php file. Optionally, but recommended. - You can remove these directories before reinstalling the core. This will help eliminate any unwanted or malicious code from your website.
