I'm not a fan of "which you must install",

Get and install ispack-5.3.4.exe which includes Inno Setup Processor,
which is necessary to package Mercurial.

I'm aware you aren't changing this line, but I don't randomly read the
source repository, i read it by reading changes to it.

Some explanations
. path is a container, things are found in it, the fact that it is
checked sequentially by the shell isn't relevant to how it's used.
. you run programs, you don't run programs with arguments.

"The installer will be placed into a directory named "Output" in your
repository."
or instead of "in" you could use "at the root of".
