 ## Container Runtime Notes
 
-- Supported Docker versions are 18.09, 19.03, 20.10, 23.0 and 24.0. The *recommended* Docker version is 20.10 (except on Debian bookworm which without supporting for 20.10 and below any more). `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 v1.25**
-- **Ansible v2.14+, Jinja 2.11+ and python-netaddr is installed on the machine that will run Ansible commands**
+- **Minimum required version of Kubernetes is v1.22**
+- **Ansible v2.11+, Jinja 2.11+ and python-netaddr is installed on the machine that will run Ansible commands**
 - 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.
-- If kubespray is run from non-root user account, correct privilege escalation method
+- If kubespray is ran from non-root user account, correct privilege escalation method
     should be configured in the target servers. Then the `ansible_become` flag
     or command parameters `--become or -b` should be specified.
