+# 인텔리제이의 모든 것 (1)
+
+### 인텔리제이에서 Kotlin 프로젝트 시작하기
+
+1. 인텔리제이 웰컴 대화상자에서 'create new project' 클릭
+
+2. 프로젝트 생성 대화상자에서 'Kotlin/JVM' 선택하고 Next를 누른다.
+
+   이를 통해 kotlinc-jvm컴파일러를 사용해서 코틀린 코드를 JVM(Java Virtual Machine)에서 실행할 수 있는 바이트코드로 변환할 수 있다. 우리는 이 과정을 '컴파일'이라고 부른다.
+

+
+
+
+3. 프로젝트 이름을 적고 프로젝트를 저장하고자 하는 디렉토리를 지정하고 finish를 누른다.
+
+4. src를 클릭하고 마우스 오른쪽 버튼을 눌러 new → Kotlin File/Class를 선택한다.
