# Unix based systems

This section describes how to install Grails on Mac OS X and Linux. You will use [SdkMan](http://sdkman.io/usage.html) to install all the requited tools.

## Step 1

Install SdkMan with this command in your console: `curl -s "https://get.sdkman.io" | bash`.

If you face to any kind of issues, open <http://sdkman.io/install.html> for help with SdkMan.

## Step 2

Open your console and install Gradle and Grails.

* `sdk install gradle`
* `sdk install grails`

Now you are done and you can proceed to another chapter about project creation.
