 ## 如何使用私有Module
 
-強制git使用ssh方式而不是https:
-
-```bash
-git config --global --add url."git@git.30cm.net:".insteadOf "https://gitea.30cm.net/"
+1. 在新項目底下加入 .cargo 目錄 並新增 config.toml 檔案
+```
+my_project/
+   ├── Cargo.toml
+   ├── src/
+   │   ├── main.rs
+   │   └── utils/
+   │       └── first_utils/
+   │           └── first.rs
+   └── .cargo/
+   └── config.toml
 ```
 
-設定go env
-
+2. 使用下列指令執行
 ```bash
-export GOPRIVATE="gitea.30cm.net"
+mkdir -p .cargo
+echo "[net]\ngit-fetch-with-cli = true" > .cargo/config.toml
 ```
+3. 在 cargo.toml 內加入下列指令，可指定分隻或者 tag 都可
+
+```toml
+[dependencies]
+utils = { git = "ssh://git@git.30cm.net/Wanderland/library-rusttgeoip.git", branch = "main" }
+```
+### 如果未產生 ssh key 連線至你的 git 的話請使用下列方式
 
 產生ssh-key
 請參考 [github ssh](https://docs.github.com/en/authentication/connecting-to-github-with-ssh) , [gitlab ssh](https://docs.gitlab.com/ee/user/ssh.html)
