put .el in a subdirectory of ~/.emacs.d/vendor

[ericlowry]

small thing, but your instructions should really have users put the your .el file into a sub directory of ~/.emacs.d/vendor/ just to avoid namespace collision (and it's a minor security issue).

You could just change your README

mkdir -p ~/.emacs.d/vendor/handlebars-mode
cd ~/.emacs.d/vendor/handlebars-mode
curl --location -O https://raw.github.com/danielevans/handlebars-mode/master/handlebars-mode.el

and

(add-to-list 'load-path "~/.emacs.d/vendor/handlebars-mode")
(require 'handlebars-mode)
