The BSD system provides useful and detailed documentation for most utilities, common configuration files, programming functions, and various procedures. These are known as manual (or man) pages and the manual may be read using the "man" command.

The manuals are categorized by various sections, usually by number but sometimes by letter or a word or other description. The standard categories are:

1 General documentation covering standard tools and utilities

2 Programmer manual pages covering system calls and definitions

3 Programmer documentation covering library functions (and subroutines)

4 Documentation covering special files, hardware devices, kernel interfaces and drivers

5 Documentation covering various binary and configuration file formats

6 Documentation for games and amusement

7 Miscellaneous documentation covering concepts and procedures not categorized in other sections.

TODO: mention "macros" and "conventions" for 7?

8 Documentation for system maintenance tools, utilities and procedures

9 Programmer documentation covering kernel interfaces and driver development
