+## 从自己的分支开始
+
+1. 拉取分支
+
+```bash
+git clone [repo.git]
+cd [repo-name]
+```
+
+2. 创建自己的分支
+
+```bash
+git checkout -b [your-name]/[do-something] # 比如 manan/dev
+```
+
+3. 首次推送分支到远程
+
+```bash
+git push -u origin [branch-name]
+```
+
+4. 本地一些改动
+
+```bash
+git add .
+git commit -m [message]
+```
+
+5. 推送改动
+
+```bash
+git push
+```
+
+## 合并到`main`
+
+确保自己的东西和`main`别差太远了，合并前，先从`main`来取并合并到自己的分支
+
+```bash
+git checkout main
+git pull # origin main
+git checkout [branch-name] # 回到特征分支
+git merge main
+```
+
+或者直接
+
+```bash
+# 确保在特征分支
+git pull origin main
+```
+
+如果冲突，会进入`([branch-name]|MERGING)` 状态
+
+解决完冲突后，继续
+
+```bash
+git merge --continue
+```
+
+大文件处理完合并后，变成指针文件，这时候用下面指令拉回
+
+```bash
+git lfs pull
+```
+
+或者退出，不解决
+
+```bash
+git merge --abort
+```
+取消曾经追踪过的文件，但不删除文件
+
+```bash
+git rm --cached [file]
+```
