# Using the Neptune ML Amazon CloudFormation template to get started quickly in a new DB cluster
<a name="machine-learning-quick-start"></a>

The easiest way to get started with Neptune ML is to use the Amazon CloudFormation quick-start template. This template installs all necessary components, including a new Neptune DB cluster, all the necessary IAM roles, and a new Neptune graph-notebook to make working with Neptune ML easier.

**To create the Neptune ML quick-start stack**

1. To launch the Amazon CloudFormation stack on the Amazon CloudFormation console, choose one of the **Launch Stack** buttons in the following table:    
[See the AWS documentation website for more details](http://docs.amazonaws.cn/en_us/neptune/latest/userguide/machine-learning-quick-start.html)

1.  On the **Select Template** page, choose **Next**.

1. On the **Specify Details** page, choose **Next**.

1. On the **Options** page, choose **Next**.

1. On the **Review** page, there are two check boxes that you need to check:
   + The first one acknowledges that Amazon CloudFormation might create IAM resources with custom names.
   + The second acknowledges that Amazon CloudFormation might require the `CAPABILITY_AUTO_EXPAND` capability for the new stack. `CAPABILITY_AUTO_EXPAND` explicitly allows Amazon CloudFormation to expand macros automatically when creating the stack, without prior review.

     Customers often create a change set from a processed template so that the changes made by macros can be reviewed before actually creating the stack. For more information, see the Amazon CloudFormation [CreateStack](https://docs.amazonaws.cn/AWSCloudFormation/latest/APIReference/API_CreateStack.html) API.

   Then choose **Create**.

The quick-start template creates and sets up the following:
+ A Neptune DB cluster.
+ The necessary IAM roles (and attaches them).
+ The necessary Amazon EC2 security group.
+ The necessary SageMaker AI VPC endpoints.
+ A DB cluster parameter group for Neptune ML.
+ The necessary parameters in that parameter group.
+ The Neptune-Export service.

You can also use the following Amazon CLI command to run the quick-start Amazon CloudFormation template:

```
aws cloudformation create-stack \
  --stack-name neptune-ml-fullstack-$(date '+%Y-%m-%d-%H-%M') \
  --template-url https://aws-neptune-customer-samples.s3.amazonaws.com/v2/cloudformation-templates/neptune-ml-nested-stack.json \
  --parameters ParameterKey=EnableIAMAuthOnExportAPI,ParameterValue={{(true if you have IAM auth enabled, or false otherwise)}} \
               ParameterKey=Env,ParameterValue=test$(date '+%H%M')\
  --capabilities CAPABILITY_IAM \
  --region {{(the Amazon region, like us-east-1)}} \
  --disable-rollback \
  --profile {{(optionally, a named CLI profile of yours)}}
```
