# How to use kanban

## Grammar
* General (H1: Kanban title\nH2: Kanban Board\nList: Kanban Task)
- Style (Supports Markdown inline styles: **bold**, *italic*, `code`, ~~delete~~, [link](https://github.com/obgnail/typora_plugin), ![Image](https://avatars.githubusercontent.com/u/48992887?s=96&v=4))
- Strict Mode (Use `use strict` on the first line to enforce strict mode; syntax errors will not be ignored.)
- Hide desc box when empty

## Settings
- Unlimited Quantity (Kanban boards and tasks are infinitely scalable.)
- Customizable Color Scheme (Customize colors in settings.)
- Long Task Lists (Scroll task lists using the mouse wheel below the Kanban board.)
- Many Kanban Boards (Scroll horizontally using Ctrl+mouse wheel.)

## NOTE
- Non Universal Grammar (Intended for temporary use in daily task management.)

2. 公式

单行使用一个$符号，换行使用两个$符号
计算公式1：$\int_{a}^{b} x^2 dx$<br>计算公式2：$\int_{a}^{b} x^3 dx$<br>$$\int_{a}^{b} x^2 dx$$
$$
Q = XW^Q, \quad K = XW^K, \quad V = XW^V
