 ## How to install it
 
 You can simply use the post-install script that you can find [here](https://github.com/aws-samples/aws-parallelcluster-monitoring/blob/main/post-install.sh) as it is, or customize it as you need. For instance, you might want to change your [Grafana password](https://github.com/aws-samples/aws-parallelcluster-monitoring/blob/main/docker-compose/docker-compose.master.yml#L43) to something more secure and meaningful for you, or you might want to customize some dashboards by adding additional components to monitor. 
-The proposed post-install script will take care of installing and configuring everything for you through the [install-monitoring.sh](https://github.com/aws-samples/aws-parallelcluster-monitoring/blob/main/install-monitoring.sh) script. Though, few additional parameters are needed in the AWS ParallelCluster config file: the post_install_args, additional IAM policies, security group, and a tag. Please note that, at the moment, the installation script has only been tested using [Amazon Linux 2](https://aws.amazon.com/amazon-linux-2/).
