The configuration file is actually a lua script which must contain an<\/p>\n

object called configuration.<\/p>\n

This will be read by the server and used to fully configure the server.<\/p>\n

Besides this object called<\/p>\n

configuration you can have functions, include other lua libraries, etc.<\/p>\n

In the end, you have to<\/p>\n

make the configuration object available. The rest of this section will<\/p>\n

explain the structue of<\/p>\n

configuration object in great detail. But first, let’s take an bird-eye<\/p>\n
