+# 동아리 활동 기록 슬랙봇
+## 개요
+- 동아리 활동 기록을 대신 적어주는 슬랙봇
+
+
+### 기능
+1. 참여 확인 메세지 전송
+  - 매일 오늘의 사서에게 사서 근무 참여 확인 메세지 전송
+  - 매주 수요일 모든 사서에게 사서 회의 참여 확인 메세지 전송
+  
+  ![확인 메세지](/docs/확인메세지.png)
+
+2. 확인 메세지 응답에 따라 활동 기록 추가
+  - "네, 활동표에 기록해주세요" 클릭시 해당 활동과 날짜, 응답자 확인후 구글 시트에 기록
+
+   ![기록 완료](/docs/기록완료메세지.png)
+
+
+### 기술스택
+- axios : http 기본 라이브러리
+- [Slack node sdk](https://slack.dev/node-slack-sdk/web-api) : 슬랙 web api 편의 라이브러리
+- [Google auth library](https://cloud.google.com/nodejs/docs/reference/google-auth-library/latest) : 구글 인증 편의 라이브러리
+
+### 실행 구조
+![구조도](/docs/구조도.png)
+- AWS Lambda : 현재 코드, 트리거 이벤트에 따라 동작
+- AWS API Gateway : 슬랙에서 사용자 interaction에 따른 POST 요청 수신, Lambda로 전달
+- AWS EventBridge : 주기적으로 이벤트 발생시키기 위한 cron job
+
+### 폴더 구조
+``` shell
+src/
+├── constants    # 기타 상수
+├── messages     # 슬랙 메세지 포맷
+├── services     # 트리거에 따라 정의된 동작
+└── utils        # 유틸함수
+index.mjs        # lambda 기본함수, 트리거에 따라 동작수행
+```
+
+### 기타 참고사항
+- 현재 레포지토리 main 브랜치에 커밋시 연결된 AWS lambda 계정 코드가 갱신되니 주의해주세요
+- AWS 계정 문의 : sujikim @notusing11
