Please use the markdown format.
Because GitHub started to support math description (link), we need to describe equations suit with the rule of GitHub and MathJax.

1. Overview

1. Features

Write an overview of features to be realized using the class or library here clearly.

2. Related files

Enumerate all related codes and input files here

3. How to use

Write how to use the class or functions

2. Explanation of Algorithm

Write important algorithms for the class, the library, or each function. Please use equations, figures, reference papers for easy understanding.

1. Name of class, structure, and function

1. Overview

Please summarize the

2. Inputs and Outputs

Please list up inputs and outputs

3. Algorithm

Please use math description when you need as follows $$\dot{\boldsymbol{x}}=f(\boldsymbol{x},t)$$

$$\dot{\boldsymbol{x}}=f(\boldsymbol{x},t)$$

you can also use inline equation as $x=y$
