Ruby on Rails is a web-framework[^framework]. It uses the MVC[^MVC] architecture pattern. It has its good points[^points].

[^framework]: a reusable set of libraries
[^MVC]: Model View Controller
[^points]: Here are its good points
     1. Ease of use
     2. Rapid development

That has nothing to do with putting equations in footnotes[^equations].

[^equations]: Like this:
$$
  x = r\cos\theta
$$
