# HyperMD Basic Example with *RequireJS*
Hate the tedious `<script>` and `<link>` tags? Use [RequireJS][] to resolve and load modules!
[RequireJS][] is a JavaScript file and module loader optimized for in-browser.
Note that HyperMD `require` css files from JavaScript. **You must apply a [CSSPatch][]** before loading.
## Summary
*Please read the source code of this page*
1. Include and Load RequireJS
2. Patch RequireJS (use [this file][CSSPatch])
3. Configure RequireJS
4. Declare [main Entry Point](https://requirejs.org/docs/api.html#data-main)
5. Ready to use
## Other
This page is using these powerpacks:
- `fold-math-with-katex`: use KaTeX to render $\TeX$ formula!
- `paste-with-turndown`: use Turndown (plus `turndown-plugin-gfm`) to convert HTML from clipboard
This page also loaded [CodeMirror sTeX mode](https://codemirror.net/mode/stex/index.html) to highlight TeX formulas.

[CSSPatch]: ../../goods/patch-requirejs.js
