 #### Usage
 
-Install Ansible according to [Ansible installation guide](/docs/ansible.md#installing-ansible)

-
 ```ShellSession

-installation location, which is the ``Location`` shown by running

 ## Container Runtime Notes
 
-- Supported Docker versions are 18.09, 19.03 and 20.10. The *recommended* Docker version is 20.10. `Kubelet` might break on docker's non-standard version numbering (it no longer uses semantic versioning). To ensure auto-updates don't break your cluster look into e.g. the YUM  ``versionlock`` plugin or ``apt pin``).
+- The list of available docker version is 18.09, 19.03 and 20.10. The recommended docker version is 20.10. The kubelet might break on docker's non-standard version numbering (it no longer uses semantic versioning). To ensure auto-updates don't break your cluster look into e.g. yum versionlock plugin or apt pin).
 - The cri-o version should be aligned with the respective kubernetes version (i.e. kube_version=1.20.x, crio_version=1.20)
 
 ## Requirements
 
-- **Minimum required version of Kubernetes is v1.24**
-- **Ansible v2.11+, Jinja 2.11+ and python-netaddr is installed on the machine that will run Ansible commands**
+- **Minimum required version of Kubernetes is v1.20**
+- **Ansible v2.9.x, Jinja 2.11+ and python-netaddr is installed on the machine that will run Ansible commands, Ansible 2.10.x is experimentally supported for now**
 - The target servers must have **access to the Internet** in order to pull docker images. Otherwise, additional configuration is required (See [Offline Environment](docs/offline-environment.md))
 - The target servers are configured to allow **IPv4 forwarding**.
 - If using IPv6 for pods and services, the target servers are configured to allow **IPv6 forwarding**.
 - The **firewalls are not managed**, you'll need to implement your own rules the way you used to.
     in order to avoid any issue during deployment you should disable your firewall.

-## 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.

-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:
