To configure the addon, you can navigate to the addon's configuration directory, located at
wos-vas/lua/wos/medalsys/config
Here, you will find two files
wos-vas/lua/wos/medalsys/config/sv_config.lua
wos-vas/lua/wos/medalsys/config/sh_config.lua
Open the file with your preferred code editor, and follow the instructions and comments located within them.
The SV_CONFIG.LUA file contains settings that should be kept secure such as your Database information, so please exercise caution when distributing or having programmers modify your server.
