-### Templates ###
-
-Yomichan uses [Handlebars](https://handlebarsjs.com/) templates for user interface generation. The source templates are
-found in the `tmpl` directory and the compiled version is stored in the `ext/bg/js/templates.js` file. If you modify the
-source templates, you will need to also recompile them. If you are developing on Linux or Mac OS X, you can use the
-included `build_tmpl.sh` and `build_tmpl_auto.sh` shell scripts to do this for you
-([inotify-tools](https://github.com/rvoicilas/inotify-tools/wiki) required). Otherwise, simply execute `handlebars
-tmpl/*.html -f ext/bg/js/templates.js` from the project's base directory to compile all the templates.

 ### Dependencies ###
 
 Yomichan uses several third-party libraries to function. Below are links to homepages, snapshots, and licenses of the exact
