+# MathJax
+
+[MathJax][1] is a beautiful and accessible way to display _mathematical content_
+in the browser, allows for writing formulas in different notations, including 
+[LaTeX][2], [MathML][3] and [AsciiMath][4], and can be easily integrated with 
+Material for MkDocs.

+
+## Configuration
+
+### Arithmatex
+
+[:octicons-file-code-24: Source][5] · [:octicons-workflow-24: Extension][6]
+
+The [Arithmatex][6] extension, which is part of of [Python Markdown
+Extensions][7], allows rendering block-style and inline equations, and can be
+enabled via `mkdocs.yml`:
+
+``` yaml
+markdown_extensions:
+  - pymdownx.arithmatex:
+      generic: true
+```
+
+Besides enabling the extension in `mkdocs.yml`, a MathJax configuration and 
+the JavaScript runtime need to be included, which can be done with [additional 
+JavaScript][8]:
+
+=== "docs/javascript/config.js"
+
+    ``` js
+    window.MathJax = {
+      tex: {
+        inlineMath: [["\\(", "\\)"]],
+        displayMath: [["\\[", "\\]"]],
+        processEscapes: true,
+        processEnvironments: true
+      },
+      options: {
+        ignoreHtmlClass: ".*|",
+        processHtmlClass: "arithmatex"
+      }
+    };
+    ```
+
+=== "mkdocs.yml"
+
+    ``` yaml
+    extra_javascript:
+      - javascripts/config.js
+      - https://polyfill.io/v3/polyfill.min.js?features=es6
+      - https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-mml-chtml.js
+    ```
+
+_MathJax can be configured in many different ways, for which Material for MkDocs 
+might not provide native support. See the [official documentation][6] for more 
+information._

+## Usage
+
+### Using block syntax
+
+When using LaTeX syntax, blocks must be enclosed in `#!latex $$...$$` on 
+separate lines:
+
+_Example_:
+
+``` latex
+$$
+\operatorname{ker} f=\{g\in G:f(g)=e_{H}\}{\mbox{.}}
+$$
+```
+
+_Result_:
+
+$$
+\operatorname{ker} f=\{g\in G:f(g)=e_{H}\}{\mbox{.}}
+$$
+
+### Using inline syntax
+
+When using LaTeX syntax, inline blocks must be enclosed in `#!latex $...$`:
+
+_Example_:
+
+``` latex
+The homomorphism $f$ is injective if and only if its kernel is only the 
+singleton set $e_G$, because otherwise $\exists a,b\in G$ with $a\neq b$ such 
+that $f(a)=f(b)$.
+```
+
+_Result_:
+
+The homomorphism $f$ is injective if and only if its kernel is only the 
+singleton set $e_G$, because otherwise $\exists a,b\in G$ with $a\neq b$ such 
+that $f(a)=f(b)$.
