Basic principles

  • Always save using the UTF-8 encoding to minimize the possibility of errors.
  • Never, EVER use the TAB character anywhere in it. This doesn't work.
  • Editing with a WYSIWYG text processor, such as Microsoft Word, is not recommended.
  • Use a monowidth/monospaced font to view the contents. Examples you may have in your computer: Fixedsys, Lucida Console, Consolas, Monaco, DejaVu Sans Mono, Courier New.

Whenever you see the # character anywhere in the file that isn't first enclosed in '' (quotes) or "" (double quotes), it marks the beginning of a comment. This means all the text after it, up until the end of the line, is completely ignored and has no effect. You can use this to write notes on the file or temporarily disable one or more options.

These are all comments:

#debug: false
#Hello there, how are you?
debug: false # <- The line is read up to this character!

This is not commented:

name: '#changeme'

But this is:

#name: '#changeme'

results matching ""

    No results matching ""
