+# 🌟 新手指南 / Beginner Guide
+
+欢迎来到 Dress 项目！这份指南将帮助你完成第一次 Pull Request（PR）。
+
+Welcome to the Dress project! This guide will help you complete your first Pull Request (PR).
+
+---
+
+## 📋 提交流程概览 / Submission Workflow Overview
+
+```
+Fork 仓库 → 添加你的照片 → 提交 Commit → 发起 Pull Request → 等待审核合并
+Fork repo → Add your photos → Commit → Open Pull Request → Wait for review & merge
+```
+
+---
+
+## 第一步：Fork 仓库 / Step 1: Fork the Repository
+
+> **Fork** = 把别人的仓库「复制」一份到你自己的 GitHub 账号下，让你可以自由修改喵，不会影响原项目喵!  
+> **Fork** = Creating your own copy of someone else's repository under your GitHub account, so you can freely make changes without affecting the original.
+
+1. 打开 [Dress 仓库页面](https://github.com/Cute-Dress/Dress)
+2. 点击页面右上角的 **Fork** 按钮
+3. 这会在你的 GitHub 账号下创建一份仓库副本
+
+---
+
+1. Go to the [Dress repository page](https://github.com/Cute-Dress/Dress)
+2. Click the **Fork** button at the top right
+3. This creates a copy of the repository under your GitHub account
+
+---
+
+## 第二步：添加你的照片 / Step 2: Add Your Photos
+
+> **Commit** = 给你的修改拍一张「快照」，记录你改了什么内容，每次 Commit 都会生成一条历史记录喵!  
+> **Commit** = Taking a "snapshot" of your changes, recording what you modified. Each commit creates a point in the project history.
+
+### 方法 A：直接在 GitHub 网页上传（最简单）/ Method A: Upload via GitHub Web (Easiest)
+
+1. 进入你 Fork 后的仓库页面（`https://github.com/<你的用户名>/Dress`）
+2. 找到你 GitHub ID 首字母对应的文件夹（如 ID 为 `Yueosa`，则进入 `Y` 文件夹）
+3. 点击 **Add file** → **Create new file**
+4. 在文件名栏输入 `你的GitHubID/README.md`（如 `Yueosa/README.md`），这会自动创建文件夹
+5. 在文件中随意写一些内容（如自我介绍）
+6. 点击 **Commit changes**
+7. 再次点击 **Add file** → **Upload files**，将你的照片上传到刚创建的文件夹中
+8. 点击 **Commit changes**
+
+---
+
+1. Go to your forked repository (`https://github.com/<your-username>/Dress`)
+2. Navigate to the folder matching the first letter of your GitHub ID (e.g., `Y` for `Yueosa`)
+3. Click **Add file** → **Create new file**
+4. Type `YourGitHubID/README.md` (e.g., `Yueosa/README.md`) in the filename field — this auto-creates the folder
+5. Write some content (e.g., a brief introduction)
+6. Click **Commit changes**
+7. Click **Add file** → **Upload files** again, and upload your photos into the folder you just created
+8. Click **Commit changes**
+
+---
+
+### 方法 B：使用 Git 命令行 / Method B: Using Git CLI
+
+> **Clone** = 把远程仓库下载到本地电脑。
+> **Push** = 把本地的 Commit 上传同步到远程仓库（你的 Fork）。  
+> **Clone** = Downloading the remote repository to your local machine. 
+> **Push** = Uploading your local commits back to the remote repository (your Fork).
+
+```bash
+# 1. 克隆你 Fork 的仓库 / Clone your forked repository
+# 💡 由于仓库 commit 历史较多，直接 clone 可能较慢。
+#    推荐使用 --depth 1 仅拉取最近一次提交，速度更快喵！
+# 💡 The repo has a large commit history, so a full clone may be slow.
+#    Consider using --depth 1 to only fetch the latest commit for a faster download!
+git clone --depth 1 https://github.com/<你的用户名>/Dress.git
+cd Dress
+
+# 2. 创建你的文件夹并添加照片 / Create your folder and add photos
+#    将 <首字母> 替换为你 GitHub ID 的首字母，<你的GitHubID> 替换为你的 GitHub ID
+#    Replace <FirstLetter> with the first letter of your GitHub ID
+mkdir -p <首字母>/<你的GitHubID>
+cp /path/to/your/photos/* <首字母>/<你的GitHubID>/
+
+# 3. 提交更改 / Commit your changes
+git add .
+git commit -m "Add photos for <你的GitHubID>"
+
+# 4. 推送到你的 Fork / Push to your fork
+git push origin main
+```
+
+---
+
+## 第三步：发起 Pull Request / Step 3: Open a Pull Request
+
+> **Pull Request（PR）** = 向原仓库的维护者提出申请：「我在我的 Fork 里做了一些修改，请把它们合并到原项目里吧喵！」  
+> **Pull Request (PR)** = A request to the original repository's maintainers saying: "I've made some changes in my Fork — please merge them into the original project!"
+
+1. 回到你 Fork 的仓库页面
+2. 你会看到一个提示 **"This branch is X commits ahead"**，点击 **Contribute** → **Open pull request**
+3. 填写 PR 模板中的描述和检查清单
+4. 点击 **Create pull request**
+
+---
+
+1. Go back to your forked repository page
+2. You should see a prompt saying **"This branch is X commits ahead"** — click **Contribute** → **Open pull request**
+3. Fill in the description and checklist in the PR template
+4. Click **Create pull request**
+
+---
+
+## 第四步：等待审核 / Step 4: Wait for Review
+
+提交 PR 后，自动化机器人会帮你检查：
+
+- 📏 **文件大小检查**：图片是否在 1MB 以内
+- 🔒 **EXIF 信息检查**：图片是否包含隐私元数据
+
+如果检查未通过，机器人会留下评论告诉你如何修正。你可以按照提示修改后再次推送（push），PR 会自动更新。
+
+维护者审核通过后，你的 PR 就会被合并。恭喜你完成了第一次开源贡献！🎉
+
+---
+
+After submitting the PR, automated bots will check:
+
+- 📏 **File size check**: Are images under 1MB?
+- 🔒 **EXIF data check**: Do images contain private metadata?
+
+If any check fails, the bot will leave a comment explaining how to fix it. You can make changes and push again — the PR will update automatically.
+
+Once a maintainer approves, your PR will be merged. Congratulations on your first open-source contribution! 🎉
+
+---
+
+## ⚠️ 提交前请注意 / Before You Submit
+
+1. **压缩图片** — 确保每张图片小于 1MB。可以使用 [TinyPNG](https://tinypng.com/) 等在线工具压缩。
+2. **移除 EXIF 信息** — 照片可能包含你的位置、设备等隐私信息。详见 [CONTRIBUTING.md](CONTRIBUTING.md)。
+3. **正确命名文件夹** — 使用你的 GitHub ID 命名，并放在对应首字母目录下。
+4. **原创图片** — 只提交你自己的照片，不接受盗图。
+
+---
+
+1. **Compress images** — Make sure each image is under 1MB. Use tools like [TinyPNG](https://tinypng.com/).
+2. **Remove EXIF data** — Photos may contain your location, device info, etc. See [CONTRIBUTING.md](CONTRIBUTING.md).
+3. **Name your folder correctly** — Use your GitHub ID and place it under the matching alphabetical directory.
+4. **Original images only** — Only submit your own photos. Stolen images are not accepted.
