+# 西北工业大学 Touying 幻灯片主题
+
+基于 Touying 构建的西北工业大学（NWPU）演示模板，使用学校官网提供的蓝色/白色校标，并以 NWPU 蓝 `#0054A3` 作为默认主色。
+
+## 快速使用
+
+```typst
+#import "@preview/touying:0.6.1": *
+#import "@preview/touying-simpl-nwpu:0.1.0": *
+
+#show: nwpu-theme.with(config-info(
+  title: [Your Title],
+  subtitle: [Your Subtitle],
+  author: [Author],
+  date: datetime.today(),
+  institution: [Northwestern Polytechnical University],
+))
+
+#title-slide()
+#outline-slide()
+
+= Section
+
+== Slide Title
+
+Slide content.
+
+== End <touying:unoutlined>
+
+#end-slide[Thank you!]
+```
+
+也可运行：
+
+```sh
+typst init @preview/touying-simpl-nwpu:0.1.0
+```
+
+## 视觉资源
+
+模板中的 NWPU 蓝色与白色校标来自西北工业大学官网。其他背景和装饰均由 Typst 原生图形生成，不依赖其他高校的视觉资源。

+/// Default slide function for the presentation.
+///
+/// - config (dictionary): The configuration of the slide. You can use `config-xxx` to set the configuration of the slide. For more several configurations, you can use `utils.merge-dicts` to merge them.
+///
+/// - repeat (int, auto): The number of subslides. Default is `auto`, which means touying will automatically calculate the number of subslides.
+///
+///   The `repeat` argument is necessary when you use `#slide(repeat: 3, self => [ .. ])` style code to create a slide. The callback-style `uncover` and `only` cannot be detected by touying automatically.
+///
+/// - setting (function): The setting of the slide. You can use it to add some set/show rules for the slide.
+///
+/// - composer (function, array): The composer of the slide. You can use it to set the layout of the slide.
+///
+///   For example, `#slide(composer: (1fr, 2fr, 1fr))[A][B][C]` to split the slide into three parts. The first and the last parts will take 1/4 of the slide, and the second part will take 1/2 of the slide.
+///
+///   If you pass a non-function value like `(1fr, 2fr, 1fr)`, it will be assumed to be the first argument of the `components.side-by-side` function.
+///
+///   The `components.side-by-side` function is a simple wrapper of the `grid` function. It means you can use the `grid.cell(colspan: 2, ..)` to make the cell take 2 columns.
+///
+///   For example, `#slide(composer: 2)[A][B][#grid.cell(colspan: 2)[Footer]]` will make the `Footer` cell take 2 columns.
+///
+///   If you want to customize the composer, you can pass a function to the `composer` argument. The function should receive the contents of the slide and return the content of the slide, like `#slide(composer: grid.with(columns: 2))[A][B]`.
+///
+/// - bodies (array): The contents of the slide. You can call the `slide` function with syntax like `#slide[A][B][C]` to create a slide.

+  config: (:),
+  repeat: auto,
