 Full-stack projects refer to projects that use Custom Web Server, SSR or BFF. These projects need to be deployed on **Vercel Functions**.
 
 In addition to configuring `vercel.json` in the same way as a [pure front-end project](#pure-front-end-project), there are two points to note for full-stack projects:
 
 1. Currently, Modern.js does not support deploying BFF projects on the Vercel platform. We will support it in future versions.
-2. When deploying on Vercel platform, the default node runtime is `20.x`, it is recommended to choose `18.x` when deploying full-stack projects,

+## Github Pages
+
+If you're creating a GitHub Pages for a repository without a custom domain, the page URL will follow this format: `http://<username>.github.io/<repository-name>`. Therefore, you need to add the following configuration in `modern.config.ts`:
+
+```
+import { defineConfig } from '@modern-js/app-tools';
+
+export default defineConfig({
+  //...
+  server: {
+    baseUrl: "/<repository-name>"
+  },
+  output: {
+    assetPrefix: "/<repository-name>",
+  }
+});
+```
+
+GitHub Pages supports two deployment ways: branch deployment or GitHub Actions deployment.
+
+For branch deployment, follow these steps:
+
+1. In the GitHub repository, navigate to Settings > Pages > Source > Deploy from a branch
+2. Install the `gh-pages` as devDependency
+3. Add the following script to `package.json`
+```
+"scripts": {
+  //...

 ## Using Self-Built Node.js Server
 
 Typically, we recommend using the built-in Node.js server of Modern.js to deploy applications. It supports hosting both pure frontend and full-stack projects, ensuring consistent performance in both development and production environments.

 全栈项目是指使用了自定义 Web Server、SSR、BFF 的项目，这些项目需要部署在 **Vercel Functions** 上。
 
 全栈项目除了按照[纯前端项目](#纯前端项目)的方式配置 `vercel.json` 外，有两点需要注意：
 
 1. 当前，Modern.js 还不支持在 Vercel 平台上部署 BFF 项目，我们将在后续的版本中支持。
-2. Vercel 平台部署时，默认 node 运行时为 `20.x`，部署全栈项目时建议选择 `18.x`，具体原因详见[Serverless Function contains invalid runtime error](https://vercel.com/guides/serverless-function-contains-invalid-runtime-error)，你可以修改 `package.json` 指定版本：

+如果你要为一个仓库常见 Github 页面，并且你没有自定义域名，则该页面的 URL 将会是以下格式：`http://<username>.github.io/<repository-name>`，所以需要在 `modern.config.ts` 中添加

+
+Github Pages 支持两种部署方式，通过分支部署或通过 Github Actions 部署，如果通过分支部署，可以使用以下步骤：
+1. 在 github 仓库中，选择 `Settings > Pages > Source > Deploy from a branch`。
+2. 安装 `gh-pages` 依赖作为开发依赖。
+3. 在 package.json 的 `scripts` 中添加 `"deploy:gh-pages": "MODERNJS_DEPLOY=ghPages modern deploy && gh-pages -d .output"`。
+4. 执行 `npm run deploy:gh-pages`。
