1. TIL을 할 레포지토리를 설정한다

1-1. GitHub Action 봇에 해당 레포지토리 쓰기 작업 권한을 부여한다

레포지토리의 Settings > Actions > General > Workflow Permissions > Read and Write permissions 선택

1-2. Personal Access Token (PAT)를 생성한다

GitHub > Settings > Developer Settings > Personal access Tokens > Generate new token

• 이 토큰에 쓰기 권한을 허용해야 한다
• 토큰을 복사한다

1-3. PAT를 레포지토리 시크릿에 추가한다

TIL할 레포지토리의 Settings > Secrets and Variables > Actions 에서 GH_PAT라는 이름의 시크릿을 생성하고, 값에 복사해둔 토큰을 붙여넣는다

2. GitHub Workflow를 추가한다

.github/workflows/update_commit.yml을 생성하고 다음을 복사한 후, github url을 적절하게 넣는다

커밋을 세고 반영하는 커밋은 반영되지 않도록 필터 로직을 추가했다
