 ## How to become a contributor and submit your own code
 
-### Environment setup
-
-It is recommended to use filter to manage the GitHub email notification, see [examples for setting filters to Kubernetes Github notifications](https://github.com/kubernetes/community/blob/master/communication/best-practices.md#examples-for-setting-filters-to-kubernetes-github-notifications)
-
-To install development dependencies you can use `pip install -r tests/requirements.txt`
-
-#### Linting
-
-Kubespray uses `yamllint` and `ansible-lint`. To run them locally use `yamllint .` and `./tests/scripts/ansible-lint.sh`
-
-#### Molecule
-
-[molecule](https://github.com/ansible-community/molecule) is designed to help the development and testing of Ansible roles. In Kubespray you can run it all for all roles with `./tests/scripts/molecule_run.sh` or for a specific role (that you are working with) with `molecule test` from the role directory (`cd roles/my-role`).
-
-When developing or debugging a role it can be useful to run `molecule create` and `molecule converge` separately. Then you can use `molecule login` to SSH into the test environment.
-
-#### Vagrant
-
-Vagrant with VirtualBox or libvirt driver helps you to quickly spin test clusters to test things end to end. See [README.md#vagrant](README.md)
-
 ### Contributing A Patch
 
 1. Submit an issue describing your proposed change to the repo in question.
 2. The [repo owners](OWNERS) will respond to your issue promptly.
 3. Fork the desired repo, develop and test your code changes.

 MetalLB hooks into your Kubernetes cluster, and provides a network load-balancer implementation. In short, it allows you to create Kubernetes services of type “LoadBalancer” in clusters that don’t run on a cloud provider, and thus cannot simply hook into paid products to provide load-balancers.
 ```

-Allows a custom defintion of worker nodes giving the operator full control over individual node flavor and
-availability zone placement. To enable the use of this mode set the `number_of_k8s_nodes` and
-`number_of_k8s_nodes_no_floating_ip` variables to 0. Then define your desired worker node configuration
-using the `k8s_nodes` variable.
-
-For example:
-```
-k8s_nodes = {
-  "1" = {
-    "az" = "sto1"
-    "flavor" = "83d8b44a-26a0-4f02-a981-079446926445"

-# AWS EBS CSI Driver
-
-AWS EBS CSI driver allows you to provision EBS volumes for pods in EC2 instances. The old in-tree AWS cloud provider is deprecated and will be removed in future versions of Kubernetes. So transitioning to the CSI driver is advised.
-
-To enable AWS EBS CSI driver, uncomment the `aws_ebs_csi_enabled` option in `group_vars/all/aws.yml` and set it to `true`.
-
-To set the number of replicas for the AWS CSI controller, you can change `aws_ebs_csi_controller_replicas` option in `group_vars/all/aws.yml`.
-
-Make sure to add a role, for your EC2 instances hosting Kubernetes, that allows it to do the actions necessary to request a volume and attach it: [AWS CSI Policy](https://github.com/kubernetes-sigs/aws-ebs-csi-driver/blob/master/docs/example-iam-policy.json)
-
-If you want to deploy the AWS EBS storage class used with the CSI Driver, you should set `persistent_volumes_enabled` in `group_vars/k8s-cluster/k8s-cluster.yml` to `true`.
-
-You can now run the kubespray playbook (cluster.yml) to deploy Kubernetes over AWS EC2 with EBS CSI Driver enabled.
-
-## Usage example
-
-To check if AWS EBS CSI Driver is deployed properly, check that the ebs-csi pods are running:
-
-```ShellSession
-$ kubectl -n kube-system get pods | grep ebs
-ebs-csi-controller-85d86bccc5-8gtq5                                  4/4     Running   4          40s

-```
-
-Check the associated storage class (if you enabled persistent_volumes):
-
-```ShellSession
-$ kubectl get storageclass
-NAME         PROVISIONER                AGE
-ebs-sc   ebs.csi.aws.com   45s
-```
-
-You can run a PVC and an example Pod using this file `ebs-pod.yml`:
-
-```yml
---
-apiVersion: v1
-kind: PersistentVolumeClaim
-metadata:
-  name: ebs-claim
-spec:
-  accessModes:
-    - ReadWriteOnce
-  storageClassName: ebs-sc

-      mountPath: /data
-  volumes:
-  - name: persistent-storage
-    persistentVolumeClaim:
-      claimName: ebs-claim
-```
-
-Apply this conf to your cluster: ```kubectl apply -f ebs-pod.yml```
-
-You should see the PVC provisioned and bound:
-
-```ShellSession
-$ kubectl get pvc
-NAME                   STATUS   VOLUME                                     CAPACITY   ACCESS MODES   STORAGECLASS   AGE

-```
-
-And the volume mounted to the example Pod (wait until the Pod is Running):
-
-```ShellSession
-$ kubectl exec -it app -- df -h | grep data
-/dev/nvme1n1   1014M   34M  981M   4% /data

 Guide:
-
 - Create instances in AWS as needed.
 - Either during or after creation, add tags to the instances with a key of `kubespray-role` and a value of `kube-master`, `etcd`, or `kube-node`. You can also share roles like `kube-master, etcd`
 - Copy the `kubespray-aws-inventory.py` script from `kubespray/contrib/aws_inventory` to the `kubespray/inventory` directory.
 - Set the following AWS credentials and info as environment variables in your terminal:
-
-```ShellSession
+```
 export AWS_ACCESS_KEY_ID="xxxxx"
 export AWS_SECRET_ACCESS_KEY="yyyyy"
 export REGION="us-east-2"
 ```
-
 - We will now create our cluster. There will be either one or two small changes. The first is that we will specify `-i inventory/kubespray-aws-inventory.py` as our inventory script. The other is conditional. If your AWS instances are public facing, you can set the `VPC_VISIBILITY` variable to `public` and that will result in public IP and DNS names being passed into the inventory. This causes your cluster.yml command to look like `VPC_VISIBILITY="public" ansible-playbook ... cluster.yml`
