## Creating an application skeleton with the Cobra generator

Let's start by creating an application called `calc-app`. We can skip the Viper configuration for now and use no license. Type the following command in the terminal below. You can use your name instead of `Gigi`

```
$ cobra init calc-app --pkg-name calc-app --license=none --viper=false --author= Gigi
```
