"# - DO NOT USE TABS. You MUST use spaces or Bukkit will complain. If\r\n" +
"# you use an editor like Notepad++ (recommended for Windows users), you\r\n" +
"# must configure it to \"replace tabs with spaces.\" In Notepad++, this can\r\n" +
"# be changed in Settings > Preferences > Language Menu.\r\n" +
"# - Don't get rid of the indents. They are indented so some entries are\r\n" +
"# in categories (like \"enforce-single-session\" is in the \"protection\"\r\n" +
"# category.\r\n" +
"# - If you want to check the format of this file before putting it\r\n" +
"# into WEPIF, paste it into http://yaml-online-parser.appspot.com/\r\n" +
"# and see if it gives \"ERROR:\".\r\n" +
