Conventions and style for documentation

Manual pages structure:

  • add references to all external commands mentioned anywhere in the text to the SEE ALSO section - also add related, not explicitly mentioned

  • the heading levels are validated - mandatory, manual page === - mandatory, sections --- - optional, sub-sections ^^^

  • command-specific examples are mostly free of restrictions but should be readable in all output formats (manual page, html)

  • subcommands are in alphabetical order

  • long command output or shell examples: verbatim output - use code-block:: directive

Quotation in subcommands:

  • exact syntax: monotype usage=0

  • reference to arguments etc: italics

  • command reference: bold btrfs filesystem show - subcommand names should be spelled in full, ie. filesystem instead of fi

  • section references: italics EXAMPLES

  • argument name in option description: caps in angle brackets <NAME> - reference in help text: caps NAME - also possible: caps italics NAME

  • command short description: - command name: bold command - optional unspecified: brackets [options] - mandatory argument: angle brackets <path> - optional parameter with argument: [-p <path>]


  • for notes use note:: directive, is rendered as a separate paragraph and should be used only for important information

  • warning:: directive is rendered as a separate paragraph and most likely more visible than NOTE, use for critical information that may cause harm, irreversible state or performance problems - should point reader to other part of documentation to seek more details
