How to add a proofreader button to your blog

You will need to edit the HTML source code of your blog. Add this line anywhere before the closing </body> tag:

<script src="//proofreader.hypervolume.com/delta-proofreader.js"></script>

Enable anonymous asks in your blog settings and add the following to your links section:

<a href="javascript: delta_proofreader()">Proofread my blog!</a>

You will also need to provide your contact email.

<a href="javascript: delta_proofreader({email:'contact email'})">Proofread my blog!</a>

If you are concerned about exposing your email, you can pass it in rot13 cipher, like this:

{email: 'contact email in rot13', encoding:'rot13'}
