 #### Linting

-Kubespray uses [pre-commit](https://pre-commit.com) hook configuration to run several linters, please install this tool and use it to run validation tests before submitting a PR.
-
-```ShellSession
-pre-commit install
-pre-commit run -a  # To run pre-commit hook on all files in the repository, even if they were not modified
-```
+Kubespray uses `yamllint` and `ansible-lint`. To run them locally use `yamllint .` and `ansible-lint`. It is a good idea to add call these tools as part of your pre-commit hook and avoid a lot of back end forth on fixing linting issues (<https://support.gitkraken.com/working-with-repositories/githooksexample/>).

-## Release note creation
-
-You can create a release note with:
-
-```shell
-export GITHUB_TOKEN=<your-github-token>
-export ORG=kubernetes-sigs
-export REPO=kubespray
-release-notes --start-sha <The start commit-id> --end-sha <The end commit-id> --dependencies=false --output=/tmp/kubespray-release-note --required-author=""
-```
-
-If the release note file(/tmp/kubespray-release-note) contains "### Uncategorized" pull requests, those pull requests don't have a valid kind label(`kind/feature`, etc.).
-It is necessary to put a valid label on each pull request and run the above release-notes command again to get a better release note)
-
-## Container image creation
-
-The container image `quay.io/kubespray/kubespray:vX.Y.Z` can be created from Dockerfile of the kubespray root directory:
-
-```shell
-cd kubespray/
-nerdctl build -t quay.io/kubespray/kubespray:vX.Y.Z .
-nerdctl push quay.io/kubespray/kubespray:vX.Y.Z
-```
-
-The container image `quay.io/kubespray/vagrant:vX.Y.Z` can be created from build.sh of test-infra/vagrant-docker/:
-
-```shell
-cd kubespray/test-infra/vagrant-docker/
-./build vX.Y.Z
-```
-
-Please note that the above operation requires the permission to push container images into quay.io/kubespray/.
-If you don't have the permission, please ask it on the #kubespray-dev channel.

 Allows a custom definition 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

 This should finish fairly quickly telling you Terraform has successfully initialized and loaded necessary modules.

-### Customizing with cloud-init

-You can apply cloud-init based customization for the openstack instances before provisioning your cluster.
-One common template is used for all instances. Adjust the file shown below:
-`contrib/terraform/openstack/modules/compute/templates/cloudinit.yaml`
-For example, to enable openstack novnc access and ansible_user=root SSH access:
-
-```ShellSession
-#cloud-config
-## in some cases novnc console access is required
-## it requires ssh password to be set
-ssh_pwauth: yes
-chpasswd:
-  list: |
-    root:secret
-  expire: False
-
-## in some cases direct root ssh access via ssh key is required
-disable_root: false
-```

 ### Provisioning cluster

 You can apply the Terraform configuration to your cluster with the following command
 issued from your cluster's inventory directory (`inventory/$CLUSTER`):

 ```ShellSession
