We'll email the code directly to you with instructions, so make sure you include your email address when making a donation.

You also need to explain what you'll be doing with the code. Personal, commercial, web site address etc.

And agree to our terms of use. This is still in preparation, but it'll look something like this: http://www.codecogs.com/pages/licences/com.php

The final documentation should be ready in a week to 10 days, so you may prefer to wait. However the license will be nothing out of the ordinary: It will license you to use the system on one website for delivery of equation for your website only.
