要在一個(gè)現(xiàn)有文件夾中啟動(dòng)Git倉(cāng)庫(kù)，只需運(yùn)行一個(gè)命令，但需注意初始化後的步驟。首先，在目標(biāo)目錄下運(yùn)行g(shù)it init創(chuàng)建新倉(cāng)庫(kù)，該命令會(huì)生成.git子目錄用於存儲(chǔ)版本跟蹤數(shù)據(jù)，但不會(huì)自動(dòng)追蹤更改；接著需手動(dòng)添加文件並提交初始版本，可使用git add .或指定具體文件後執(zhí)行g(shù)it commit -m "Initial commit"完成提交；最後（可選但推薦）將本地倉(cāng)庫(kù)連接到遠(yuǎn)程服務(wù)器如GitHub，通過(guò)git remote add origin 綁定遠(yuǎn)程倉(cāng)庫(kù)，並用git push -u origin master推送代碼。初始化錯(cuò)誤時(shí)可刪除.git文件夾撤銷(xiāo)操作，且推送首次後即可直接使用git push。

You just need to run a single command to start a Git repo in an existing folder — but there are a few things worth knowing before and after that step.

Run git init to create a new repository

If you're already inside the directory where you want to set up version control, just type:

 git init

This creates a .git subdirectory in your current folder — that's where all the version tracking data lives. Once initialized, Git is ready to track changes, but it won't do anything automatically. You still need to add files and make commits manually.

A common mistake here is running git init in the wrong directory. If that happens, just delete the .git folder ( rm -rf .git ) to undo the initialization.

Add files and make your first commit

After initializing, you'll typically do two things: add files and commit them. Here's how:

• Stage all files in the directory:

   git add .

• Or, stage specific files:

   git add file1.txt file2.js

Then create your first commit:

 git commit -m "Initial commit"

That's it — you've officially recorded the state of your project in Git. It's normal for this step to feel minimal. Git doesn't check file contents again until you tell it to.

Set up a remote repository (optional but recommended)

At this point, your repo is local only. If you plan to collaborate or back up your code, connect it to a remote server like GitHub or GitLab.

First, create an empty repo on the platform (don't initialize with a README). Then copy the remote URL and link it:

 git remote add origin https://github.com/yourusername/your-repo.git

Finally, push your work:

 git push -u origin master

From now on, you can use just git push since the upstream branch is set.

That's the basic flow — initialize, add, commit, and optionally push. It's simple, but easy to misstep if you're not careful with which files you add or where you run the commands.
