+# k3s playbook
+
+## Introduction
+
+This is the top level playbook for the 'k3s' role and will install a k3s
+cluster to three or more target hosts.
+
+This playbook requires at least three target hosts, previously deployed. Each
+host should have at least 4GB of RAM and at least a 20GB disk.
+
+It is also assumed that the user running the playbook has SSH key access
+set up for the root user on the target hosts.
+
+NOTE: If you are installing in a proxied environment, make sure that you
+      have either 'HTTP_PROXY' or 'HTTPS_PROXY' (case is not important)
+      defined in your env variables (usually via ~/.bashrc). In addition
+      to that, you also need to have 'NO_PROXY' (again, case is not
+      important) also defined. This is where the k3s installer will
+      retrieve the relevant proxy configuration values.
+
+This playbook can be run using the following command line;
+
+    ansible-playbook -i <inventory file> -e "username=<username>" k3s.yml
+
+    ie,
+    ansible-playbook -i k3s_inventory.yml -e "username=ubuntu" k3s.yml
+
