I am trying to follow edits made in a php file to patch a module and the instructions just say "In your database schema add this", which I could do if I knew where to find the file. When I look up drupal database schema it shows a map which doesn't help me to find the file. What do they mean exactly by in your database schema and how can I access this file in terminal? Is it by editing a table in the database?
I can find the other file alright to edit in /includes/database/mysql/schema.inc file but just not the specific module one.
The instructions for this vchess module patch are here
