-@item{@bold{Windows} users: when you see instructions that reference @exec{racket} or @exec{raco}, I'll trust you to convert into the appropriate command for your system. Assuming defaults, it's likely to be @filepath{C:\Program Files\Racket\raco} (include the surrounding quotes in the command).}

-@item{@bold{Mac OS} users who haven't altered your @envvar{PATH} before: don't panic. You need to add the full path of Racket's @filepath{bin} subdirectory to the @filepath{/etc/paths} file on your system. 
-
-First, confirm that your Racket instal­la­tion works. Open your new Racket direc­tory and launch­ DrRacket. If DrRacket works, then your Racket installa­tion is sound.
-
-Second, verify the full path to the @filepath{bin} sub­di­rec­tory of your new Racket direc­tory. If you put this direc­tory in @filepath{Applications} as rec­om­mended, the path will be:
-
-@terminal{/Applications/Racket v@(short-version)/bin}
-
-Third, copy the terminal command below, paste it into your terminal, and type return. (It will ask you for your password, because the @filepath{paths.d} directory is restricted to administrators.)
-
-@terminal{sudo sh -c 'echo "/Applications/Racket v@(short-version)/bin" >> /etc/paths.d/racket'
-}
-
-Of course, @filepath{/Applications/Racket v@(short-version)/bin} in this command should be edited as necessary to represent the actual location and version of your Racket installation.}
