+# [M-Jaxon](https://github.com/Enter-tainer/m-jaxon)
+
+Render LaTeX equation in typst using MathJax.
+
+**Note:** This package is made for fun and to demonstrate the capability of typst plugins.
+And it is **slow**. To actually convert LaTeX equations to typst ones, you should use **pandoc** or **texmath**.

+
+````typ
+#import "./typst-package/lib.typ" as m-jaxon
+// Uncomment the following line to use the m-jaxon from the official package registry
+// #import "@preview/m-jaxon:0.1.1"
+
+= M-Jaxon
+
+Typst, now with *MathJax*.
+
+The equation of mass-energy equivalence is often written as $E=m c^2$ in modern physics.
+
+But we can also write it using M-Jaxon as: #m-jaxon.render("E = mc^2", inline: true)
+
+````
+
+## Limitations
+
+- The baseline of the inline equation still looks a bit off.
+
+
+## Documentation
+
+### `render`
+
+Render a LaTeX equation string to an svg image. Depending on the `inline` argument, the image will be rendered as an inline image or a block image.
+
+#### Arguments
+
+* `src`: `str` or `raw` block - The LaTeX equation string
+* `inline`: `bool` - Whether to render the image as an inline image or a block image
+
+#### Returns
+
+The image, of type `content`
