Retypeset is a static blog theme based on the [Astro](https://astro.build/) framework. This guide introduces how to modify theme configuration and create new articles, helping you quickly set up your personal blog.

## Theme Configuration

Customize your blog by modifying the configuration file [src/config.ts](https://github.com/radishzzz/astro-theme-retypeset/blob/master/src/config.ts).

### Site Information

```ts
site: {
  // site title
  title: 'Retypeset'
  // site subtitle
  subtitle: 'Revive the beauty of typography'
  // site description
  description: 'Retypeset is a static blog theme...'
  // use i18n title/subtitle/description from src/i18n/ui.ts instead of static ones above
  i18nTitle: true // true, false
  // author name
  author: 'radishzz'
  // site url
  url: 'https://retypeset.radishzz.cc'

    secondary: 'oklch(40% 0.005 298)'
    // background color
    background: 'oklch(96% 0.005 298)'

  cjk: number // Chinese, Japanese, Korean
  other: number // Other languages

  list: { // Homepage post list
