 # SwiftUIMath
+<!-- TODO: Badges -->
+Render LaTeX-style math expressions natively in SwiftUI.
+
+SwiftUIMath provides a small, focused SwiftUI API for displaying mathematical expressions across Apple platforms.

+
+## Motivation
+
+SwiftUIMath aims to make math expressions feel native in SwiftUI. It provides a small, focused API that renders math
+directly and integrates naturally with SwiftUI across Apple platforms.
+
+## Features
+
+- Native SwiftUI `Math` view
+- Inline and display math typesetting
+- Bundled, high-quality math fonts
+- Monochrome rendering (respects `foregroundStyle`)
+- Multicolor rendering (honors LaTeX color commands)
+- Vector-based, native rendering
+
+## Minimum requirements
+
+You can use SwiftUIMath on the following platforms:
+
+- iOS 17+
+- macOS 14+
+- tvOS 17+
+- watchOS 10+
+- visionOS 1.0+
+
+## Getting started
+
+The simplest way to render math is with the `Math` view:
+
+```swift
+Math("x^2 + y^2 = z^2")
+```
+
+By default, math is rendered in *display style*. You can control the typesetting style using a view modifier:
+
+```swift
+Math("\\int_0^1 x^2\\,dx = \\frac{1}{3}")
+  .mathTypesettingStyle(.text)
+
+Math("\\frac{1}{2} + \\sqrt{2}")
+  .mathTypesettingStyle(.display)
+```
+
+## Styling math
+
+SwiftUIMath keeps styling explicit and predictable. There are three main knobs: font, typesetting style, and
+rendering mode.
+
+### Fonts
+
+SwiftUIMath ships with a curated set of bundled math fonts, exposed via `Math.Font`.
+
+```swift
+Math("\\sum_{i=1}^{n} x_i")
+  .mathFont(Math.Font(name: .latinModern, size: 24))
+```
+
+You can check [`Font.swift`](./Sources/SwiftUIMath/Font.swift) for the available bundled fonts.
+
+### Rendering mode
+
+SwiftUIMath supports two rendering modes: `monochrome` (the default) and `multicolor`.
+
+In monochrome mode, `Math` respects the surrounding SwiftUI foreground style.
+
+```swift
+Math("E = mc^2")
+  .foregroundStyle(.blue)
+```
+
+This mode is ideal when math should blend naturally with surrounding text.
+
+Multicolor mode honors LaTeX color commands such as `\color` and `\textcolor`. Currently, only hex colors
+(e.g. `#RRGGBB`) are supported.
+
+```swift
+Math("\\color{#cc0000}{a}+\\color{#00aa00}{b}+\\color{#0000cc}{c}")
+  .mathRenderingMode(.multicolor)
+```
+
+In multicolor mode:
+
+- Explicit LaTeX colors are preserved
+- Uncolored glyphs use a base color (`Color.primary` by default)
+
+## Scope
+
+SwiftUIMath focuses on rendering LaTeX math-mode expressions.
+
+It is designed for displaying mathematical notation in SwiftUI views, not for typesetting full LaTeX documents or
+evaluating expressions. While it supports a wide range of common math constructs, not all LaTeX commands are
+implemented.
+
+## Installation
+
+You can add SwiftUIMath to an Xcode project by adding it to your project as a package.
+
+> https://github.com/gonzalezreal/swiftui-math
+
+If you want to use SwiftUIMath in a [SwiftPM](https://swift.org/package-manager/) project, it's as
+simple as adding it to your `Package.swift`:
+
+``` swift
+dependencies: [
+  .package(url: "https://github.com/gonzalezreal/swiftui-math", from: "0.1.0")
+]
+```
+
+And then adding the product to any target that needs access to the library:
+
+```swift
+.product(name: "SwiftUIMath", package: "swiftui-math"),
+```
+
+## Acknowledgments
+
+SwiftUIMath builds on prior work in native math rendering on Apple platforms:
+
+- [iosMath](https://github.com/kostub/iosMath) laid the groundwork for native math layout and rendering.
+- [SwiftMath](https://github.com/mgriebling/SwiftMath) brought these ideas into the Swift ecosystem and inspired
+  this project.
+
+This work would not be possible without the contributions of these projects.
