這個改動有點大，能說明詳細一點，給沒用過 Travis CI 的人了解嗎？
另外也在 Readme 中解釋一下整個流程？

[irvin]

除了 CNAME 外的新檔案擋頭補一下註解？

[yoyo930021]

新檔案檔頭 已經加上註解
Readme 也補上相關說明

並已寫好加入 patch

[irvin]

@yoyo930021 有改了 package.json，那本機跑 npm start 開發環境會被影響嗎？

[irvin]

是不是要 deploy 到 gh-pages 去？

[yoyo930021]

這邊沒錯 它的意思是 deploy 要基於 production branch
如果不是 不要部署
https://docs.travis-ci.com/user/deployment

[irvin]

測試期間先指到 beta.moztw.space
等正式要轉移我再去請 piaip 幫忙改 DNS 設定

[yoyo930021]

好 等等有空修

[yoyo930021]

不會影響舊有的 npm run start

[yoyo930021]

有發現新 bug 會在晚一點修

should use GitHub Actions instead.

Run git apply and paste the following code into your terminal to create the workflow file.

diff --git a/.github/workflows/gh-pages.yml b/.github/workflows/gh-pages.yml
