+## 如何新增Module
+
+假設新增一個module叫 monitoring/grafana
+
+- init
+
+```bash
+mkdir -p monitoring/grafana
+cd ./monitoring/grafana
+go mod init yt.com/backend/common.git/monitoring/grafana
+go work use ./monitoring/grafana
+```
+
+- befor commit
+
+建議測試覆蓋率盡量達到80%
+
+```bash
+before-commit-check
+```
+
+- commit
+
+```bash
+git add ./monitoring/grafana
+git commit -m "feat: add monitoring/grafana module"
+git tag "monitoring/grafana/v1.0.0"
+git push origin monitoring/grafana/v1.0.0
+```
+
+- launch merge request and codereview
+
+## 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@code.30cm.net:".insteadOf "https://code.30cm.net/"
+
+# 檢查語法
+vim ~/.gitconfig
+```
+
+設定go env
+
+```bash
+export GOPRIVATE="code.30cm.net"
+```
+
+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)
+
+add ssh key to the ssh-agent
+請參考 [Adding your SSH key to the ssh-agent](https://docs.github.com/en/authentication/connecting-to-github-with-ssh/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent#adding-your-ssh-key-to-the-ssh-agent)
+
+```bash
+$ eval "$(ssh-agent -s)"
+> Agent pid 59566
+```
+
+```bash
+$ touch ~/.ssh/config
+```
+
+```
+Host code.30cm.net
+  Hostname code.30cm.net
+  User Daniel.W
+  IdentityFile ~/.ssh/id_rsa
+```
+
+```bash
+$ ssh-add --apple-use-keychain ~/.ssh/id_ed25519
+```
+
+使用 yt.com domain， git clone repo
+
+```bash
+git clone git@code.30cm.net:backend/layout-template.git
+```
+
+在自己repo底下執行:
+
+```bash
+go clean -modcache
+go mod tidy
+
+or
+go get -x yt.com/backend/common.git/transport/http/health@1.0.0
+```
