Each framework uses different table names. With convars you can adjust users, owned_vehicles and BSN source without changing code.
By default, meosify-meos expects ESX-like tables: users, owned_vehicles, owned_properties and user_licenses.
Use meosify_sync_users_table and related convars in server.cfg if your framework uses different names.
For BSN via fingerprint table, set meosify_bsn_source to fingerprint and configure the join columns. Everything stays in server.cfg — no config.lua in the download.
