自2022年5月以来，这已得到官方支持:

内联:

Where $x = 0$, evaluate $x + 1$

块:

Where
$$x = 0$$

Evaluate
$$x + 1$$

编辑:正如锗指出的那样，它对README不起作用。Md但其他git页面，虽然没有解释可用。 我的快速解决方案是这样的

步骤1。将latex添加到.md文件中

$$x=\sqrt{2}$$

注意:数学公式必须在$$…$$或\\(…\ \)。

步骤2。将以下代码添加到scripts.html或主题文件中(将此代码附加在末尾)

<script type="text/javascript" async

src="https://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-MML-AM_CHTML">

完成了!。通过加载页面查看你的等式。

您还可以看看我的工具latexMarkdown2Markdown，它可以将LaTeX转换为SVG并生成带有章节编号的内容表。

好消息! 根据这篇博文，现在GitHub在自述文件中支持Mathjax。

可以使用$分隔符使用内联LaTeX语法，或者使用$$分隔符使用块内语法。

我测试了其他人提出的一些解决方案，我想推荐TeXify在agurodriguez的评论中创建和提出，并由Tom Hale进一步描述-我想发展他的答案，并给出一些理由，为什么这是一个非常好的解决方案:

TeXify is wrapper of Readme2Tex (mention in Lee answer). To use Readme2Tex you must install a lot of software in your local machine (python, latex, ...) - but TeXify is github plugin so you don't need to install anything in your local machine - you only need to online installation that plugin in you github account by pressing one button and choose repositories for which TeXify will have read/write access to parse your tex formulas and generate pictures. When in your repository you create or update *.tex.md file, the TeXify will detect changes and generate *.md file where latex formulas will be exchanged by its pictures saved in tex directory in your repo. So if you create README.tex.md file then TeXify will generate README.md with pictures instead tex formulas. So parsing tex formulas and generate documentation is done automagically on each commit&push :) Because all your formulas are changed into pictures in tex directory and README.md file use links to that pictures, you can even uninstall TeXify and all your old documentation will still works :). The tex directory and *.tex.md files will stay on repository so you have access to your original latex formulas and pictures (you can also safely store in tex directory your other documentation pictures "made by hand" - TeXify will not touch them). You can use equations latex syntax directly in README.tex.md file (without loosing .md markdown syntax) which is very handy. Julii in his answer proposed to use special links (with formulas) to external service e.g . http://latex.codecogs.com/gif.latex?s%3D%5Ctext%20%7B%20sensor%20reading%20%7D which is good however has some drawbacks: the formulas in links are not easy (handy) to read and update, and if there will be some problem with that third-party service your old documentation will stop work... In TeXify your old documentation will works always even if you uninstall that plugin (because all your pictures generated from latex formulas are stay in repo in tex directory). The Yuchao Jiang in his answer, proposed to use Jupyter Notebook which is also nice however have som drawbacks: you cannot use formulas directly in README.md file, you need to make link there to other file *.ipynb in your repo which contains latex (MathJax) formulas. The file *.ipynb format is JSON which is not handy to maintain (e.g. Gist don't show detailed error with line number in *.ipynb file when you forgot to put comma in proper place...).

这里是我的一些回购的链接，我使用TeXify的文档是从README.tex.md文件生成的。

更新

今天2020.12.13我意识到TeXify插件停止工作-即使重新安装后:(

如果你对https://www.codecogs.com/latex/eqneditor.php有问题，我发现https://alexanderrodin.com/github-latex-markdown/对我有用。它生成您需要的Markdown代码，因此您只需将其剪切并粘贴到README中。md文档。
