# Reference

This section contains information about the more technical side of Opus - the internal commands and arguments, wildcard pattern matching syntax, codes for configuring the status bar, scripting, etc.

Please treat this section as a reference guide only - it is not intended to be read as a tutorial for raw beginners. Most pages in this section will link back to the main help file where concepts are introduced and explained in much greater detail.
