## Getting Started

### Introduction

[LaTeX](https://www.latex-project.org/) A TEX-based typesetting system suitable for producing scientific, mathematical,
and physical documents of high print quality.

- [LaTeX official website](https://www.latex-project.org/) _(latex-project.org)_
- [KaTeX official website](https://katex.org/) _(katex.org)_

And [KaTeX](https://katex.org/) handles only a smaller subset of LaTeX's mathematical notation for display on the web

### Example

```KaTeX
% \f is defined as #1f(#2) using the macro
f\relax(x) = \int_{-\infty}^\infty
    f\hat\xi\,e^{2 \pi i \xi x}
    \,d\xi
```

    f\hat\xi\,e^{2 \pi i \xi x}
    \,d\xi
```

### Inline

```markdown
Based on KaTeX in one lineExample  
Example： `KaTeX:\int_0^\infty x^2 dx`
```

Example based on KaTeX showing on one line: `KaTeX:\int_0^\infty x^2 dx`
