+## 建立 Git Submodule
+```
+git submodule add <repository> [<path>]
+```
+新增之後，用 git status 會發現多了兩個東西需要 commit：
+![[Pasted image 20220608152709.png]]
+
+第一個檔案 .gitmodules，裡面紀錄 submodule 的對應關係，內容大概像這樣：
+```
+[submodule "RobotRunQA"]
+        path = RobotRunQA
+        url = git@github.com-logi:JuiwenHsu/RobotRunQA.git
+```
+
+接下來剩3個步驟：
+1. 提交 `.gitmodule`：`git add .gitmodule ; git push origin master`
+2. 跟git說我們有新增一個submodule：`git submodule init`
+3. 把submodule pull下來：`git submodule update`
+
+## Clone repository and submodule
+當clone一個有submodule的repo的時候，我們還需要 `git submodule init` 跟 `git submodule update` ，例如：
+```
+git clone https://xxx/xxx.git 
+cd xxx
+git submodule init
+git submodule update
+```
