There are two files

• settings.gradle.kts
• build.gradle.kts

Command to start a gradle project

• gradle init

If we are building an executable app, pick 2:application If we are creating a library that will be used by others, pick 3:library If we are building gradle plugin to offer more functionality, pick 4:gradle plugin If we pick 1: basic, this gradle will create a basic layout and configuration, this is the default option

if we are asked how many subprojects will be in our application, we will specify "no" to indicate only 1

For the demo video: project name: calc source package name: com.gradlelab
