Bookmarklet that allows me to add a link to more information for specific emails I receive

I receive a number of periodic emails that prompt me to do something (e.g. take an electricity meter reading). I wanted to be able to add information to those emails to remind me how to perform the task.

This JavaScript allows me to configure rules so that I can display a link to a web page when I'm viewing an email with a specific subject in Gmail.

I'm currently hosting the JavaScript and installer web page using rawgit.com.

Visit this page to install the bookmarklet.
