## Step 3

You are going to set Java home in this step, because Grails is Java based technology and you need Java on system in order to run any Grails command. Insert **JAVA\_HOME** into *Variable name* text field. Then insert path to your version of Java 8 into *Variable value* text field.

## Step 4

In this step we are going to set Grails home because you will need to run Grails commands from command line.

Insert **GRAILS\_HOME** into *Variable name* text field and path to Grails installation into *Variable value* text field. You can get Grails binaries from <https://grails.org/download.html>. Just unzip the downloaded archive and provide path to the folder. In our case, it was `grails-3.1.7` on `C:` drive.

## Step 5

In this step you will make it possible to run Grails from your command line. Select *Path* variable from the list of system variables and click on *Edit...* button. Go at the end of text in *Variable value* text field and append the path to Grails `bin` folder, in our case `C:\grails-3.1.7\bin`
