+Chrony NTP server
+
+[Chrony website/documentation](https://chrony.tuxfamily.org/)
+
+[Ubuntu Chrony docs](https://ubuntu.com/blog/ubuntu-bionic-using-chrony-to-configure-ntp)
+
+## Requirements
+
+Minimum ansible version: 2.9.5
+
+## Configuration
+
+Add the NTP servers you want to use to the `ntp_pools` list, with a count of
+servers per pool.
+
+Add a list of CIDR formatted IP ranges to `ntp_client_allow`, and those systems
+will be able to request time information from the server.
+
+## Example Playbook
+
+```yaml
+- hosts: all
+ vars:
+ ntp_pools:
+ - name: 0.pool.ntp.org
+ count: 1
+ - name: 1.pool.ntp.org
+ count: 1
+ - name: 2.pool.ntp.org
+ count: 1
+ - name: 3.pool.ntp.org
+ count: 1
+ ntp_client_allow:
+ - "10.0.0.1/24"
+ roles:
+ - chrony
+```
