+## 1 단계 - GitHub(모듈 분리)
+### 프로그래밍 요구 사항
+- 순수 코틀린 모듈인 domain 모듈을 만든다.
+- 순수 코틀린 모듈인 data 모듈을 만든다.
+- data 모듈은 domain 모듈에 의존해야 한다.
+- app 모듈은 domain 모듈에 의존해야 한다.
+
+## 2단계 - GitHub(HTTP)
+###기능 요구사항
+- GitHub Repository 목록을 가져올 수 있어야 한다.
+- GET, https://api.github.com/repositories
+- full_name, description 필드만
+
+###프로그래밍 요구사항
+- Repository 목록을 가져오는 기능은 data 모듈에 구현되어야 한다.
+- data 모듈의 구현체는 모두 internal class로 선언한다.
+- HTTP 요청을 통해 가져오는 구현체에 대한 테스트 코드를 작성한다.
+- OkHttp MockWebServer 이용
