## Before you begin

- You can learn about the concept of chaos infrastructures & chaos environments [here](../concepts/infrastructure.md).

- You will need to create an environment for your chaos infrastructure to reside within. Environments are an abstraction layer over infrastructures, and a detailed guide on the environment creation process can be found [here](./create-environment.md)

## 1. Go to the Infrastructure section

Navigate to the `/environments` page (Environments on the left nav), and click on the environment you wish to install the chaos infrastructure in:

## 2. Enable Chaos

Click on the `Enable Chaos` button:

## 3. Add details of the Infrastructure

Add the details of the infrastructure such as the name, description and tags, then click on the `Next` button:

## 4. Tune the cluster level specifications

Choose one of the following modes:

- **Cluster Wide:** This mode of infrastructure installation allows targeting resources across the entire cluster, in all the namespaces, as part of an experiment.
- **Namespace Mode:** This mode of infrastructure installation allows targeting resources only in the namespace where the chaos infrastructure is deployed.

By default the installation will take place in the `litmus` namespace and uses `litmus` service account, which can be configured under the K8s cluster details.

Optionally, you can also specify the node selectors and Kubernetes tolerations for chaos infrastructure deployment in the advanced section

## 5. Deploy your Chaos Infrastructure

- For cluster-wide access:

<ol type="a">
  <li>Select Download, and then copy and run the kubectl command shown on your screen to install the chaos infrastructure.</li>
</ol>

<img src={require('../assets/user-guides/infrastructure/create-infrastructure/step-5.png').default} />

- For namespace access:

<ol type="a">
  <li>Run the first kubectl command to create the target namespace.</li>
  <li>Run the second kubectl command to apply the chaos CRDs.</li>
  <li>Select Download, and then copy and run the third command to install the chaos infrastructure.</li>
</ol>

Click `Done`

The newly created infrastructure will appear in the list of infrastructures:
