+# texst
+
+`TeXst` is a Typst package for LaTeX-like academic paper formatting.
+
+## Start Here
+
+Use one of these package imports:
+
+1. Published package (Typst Universe):
+
+```typst
+#import "@preview/texst:0.1.0": paper
+```
+
+2. Local package install:
+
+```typst
+#import "@local/texst:0.1.0": paper
+```
+
+## Manual Install (No `@preview`)
+
+If you download the repo manually, you can install it as a local Typst package:
+
+1. Download and unzip this repository.
+2. Copy its contents into this folder structure:
+   - macOS: `~/Library/Application Support/typst/packages/local/texst/0.1.0/`
+   - Linux: `~/.local/share/typst/packages/local/texst/0.1.0/`
+   - Windows: `%APPDATA%\\typst\\packages\\local\\texst\\0.1.0\\`
+3. Import from `@local` in your Typst file:
+
+```typst
+#import "@local/texst:0.1.0": paper
+```
+
+## Fastest Way to Use It
+
+Copy this into your `main.typ`:
+
+```typst
+#import "@preview/texst:0.1.0": paper
+
+#show: doc => paper(
+  title: [Paper Title],
+  subtitle: [Optional Subtitle],
+  authors: (
+    (name: [Author One]),
+    (name: [Author Two]),
+  ),
+  date: datetime.today().display("[month repr:long] [day], [year]"),
+  abstract: [Write a concise abstract here.],
+  doc,
+)
+
+#outline(title: [Contents])
+
+#heading(level: 1)[Introduction]
+
+Start writing your paper.
+
+#heading(level: 1)[Appendix]
+
+#heading(level: 2)[Additional Material]
+
+Add supplementary details here.
+```
+
+## Initialize a Template Project
+
+```bash
+typst init @preview/texst:0.1.0
+```
+
+This generates a starter project from `template/main.typ`.
+
+## What `paper(...)` Does
+
+`paper(...)` applies:
+- page layout and numbering
+- typography defaults
+- heading style and spacing
+- table/figure alignment and numbering
+- equation and reference behavior
+- title block and abstract formatting
+
+Your document content is passed through `doc`.
+
+## Public API
+
+- `paper(title:, subtitle:, authors:, date:, abstract:, style:, doc)`
+- `nneq(eq)` (unnumbered display equation)
+- `caption-note(body)`
+- `caption-with-note(title, note)`
+- `table-note(body)`
+- `theorem`, `proof`, `prop`, `lem`, `rem`, `asp`
+
+## Style Overrides
+
+Pass a `style` dictionary to override defaults:
+
+```typst
+#show: doc => paper(
+  title: [Styled Paper],
+  style: (
+    body_font: "Libertinus Serif",
+    page_margin: (x: 1in, y: 1in),
+    heading_numbering: "1.",
+    accent_main: rgb(20, 40, 120),
+  ),
+  doc,
+)
+```
+
+Common keys include:
+- `page_margin`, `page_numbering`
+- `body_font`, `body_size`
+- `paragraph_leading`, `paragraph_indent`
+- `heading_numbering`, `heading_size`, `heading_weight`
+- `footnote_numbering`, `accent_main`
+
+## Local Development
+
+- `examples/minimal.typ` is the local smoke test.
+- `template/main.typ` is the package template entrypoint.
+- Compile locally:
+
+```bash
+typst compile --root . examples/minimal.typ /tmp/minimal.pdf
+```
