 This repo hosts the `community.kubernetes` Ansible Collection.

+## Installation and Usage
+
+### Installing the Collection from Ansible Galaxy
+
+Before using the Kuberentes collection, you need to install it with the Ansible Galaxy CLI:
+
+    ansible-galaxy collection install community.kubernetes
+
+You can also include it in a `requirements.yml` file and install it via `ansible-galaxy collection install -r requirements.yml`, using the format:
+
+```yaml
+---
+collections:
+  - name: community.kubernetes
+    version: 1.0.0
+```
+
+### Using modules from the Kubernetes Collection in your playbooks
+
+You can either call modules by their Fully Qualified Collection Namespace (FQCN), like `community.kubernetes.k8s_info`, or you can call modules by their short name if you list the `community.kubernetes` collection in the playbook's `collections`, like so:
+
+```yaml
+---
+- hosts: localhost
+  gather_facts: false
+  connection: local
+
+  collections:
+    - community.kubernetes
+
+  tasks:
+    - name: Get a list of all pods in the kube-system namespace.
+      k8s_info:
+        kind: Pod
+        namespace: kube-system
+      register: system_pods
+
+    - name: Display pod information for pods in kube-system namespace.
+      debug:
+        var: system_pods.resources | count
+
+```
+
+For documentation on how to use individual modules and other content included in this collection, please see the links in the 'Included content' section earlier in this README.
+
+## Testing and Development
+
+If you want to develop new content for this collection or improve what's already here, the easiest way to work on the collection is to clone it into one of the configured [`COLLECTIONS_PATHS`](https://docs.ansible.com/ansible/latest/reference_appendices/config.html#collections-paths), and work on it there.
+
+The `tests` directory contains configuration for running sanity and integration tests using [`ansible-test`](https://docs.ansible.com/ansible/latest/dev_guide/testing_integration.html).
+
+You can run the collection's test suites with the commands:
+
+    ansible-test sanity --docker -v --color
+    ansible-test integration --docker -v --color
+
