+title: Configuration Reference
+---
+
+To configure Astro, add an `astro.config.mjs` file to the root of your project.
+
+```js
+export default /** @type {import('astro').AstroUserConfig} */ ({
+  // all options are optional; these values are the defaults
+  projectRoot: './',
+  public: './public/',
+  dist: './dist/',
+  src: './src/',
+  pages: './pages/',
+  renderers: [
+    '@astrojs/renderer-svelte',
+    '@astrojs/renderer-vue',
+    '@astrojs/renderer-react',
+    '@astrojs/renderer-preact',
+  ],
+  vite: {},
+});
+```
+
+#### projectRoot
+
+The `projectRoot` option sets the working directory used by Astro. Astro will resolve all other directory options from this path.
+
+**Default**: The current working directory.
+
+#### public
+
+The `public` option sets the directory used to resolve public assets. Astro does not process any files within this directory.
+
+**Default**: The `public` directory within the `projectRoot` directory.
+
+#### dist
+
+The `dist` option sets the directory used to output the final build of the project. Contents of the `public` directory are also copied into this directory.
+
+**Default**: The `dist` directory within the `projectRoot` directory.
+
+#### src
+
+The `src` option sets the directory used to resolve source files, like `pages`. Astro may process, optimize, and bundle any files in this directory.
+
+**Default**: The `src` directory within the `projectRoot` directory.
+
+#### pages
+
+The `pages` option sets the directory used to resolve pages, relative to the `src` option.
+
+**Default**: The `pages` directory within the `src` directory.
+
+#### renderers
+
+The `renderers` option defines the framework renderers to be used by Astro.
+
+**Default**: An array of `@astrojs/renderer-svelte`, `@astrojs/renderer-vue`, `@astrojs/renderer-react`, and `@astrojs/renderer-preact`. To assign no renderers at all, you must provide an empty array (`[]`).
+
+#### buildOptions
+
+The `buildOptions` option configures how a site is built, including its base URL (`buildOptions.site`), whether it includes a sitemap (`buildOptions.sitemap`), and whether its pages should be files (`path.html`) or directories (`path/index.html`) (`buildOptions.pageUrlFormat`).
+
+#### devOptions
+
+The `devOptions` option configures features used during development, including the server hostname (`devOptions.hostname`), the server port (`devOptions.port`), and whether urls should include a trailing slash (`devOptions.trailingSlash`).
+
+#### vite
+
+The `vite` option configures the internals of Vite. These options can be explored on [ViteJS.dev](https://vitejs.dev/config/).
+
+#### markdownOptions
+
+The `markdownOptions` option assigns options to the Markdown parser. These options can be explored on [GitHub](https://github.com/withastro/astro/blob/latest/packages/astro/src/@types/astro.ts).
