+## Introduction
 
 The nri-plugins-operator is an Ansible-based operator created with operator-sdk to manage the life cycle of the
 nri-plugins. The operator deploys community maintained [nri-plugins](https://github.com/containers/nri-plugins) in
 Kubernetes cluster. When operator is installed, it doesn't do anything apart from watching for custom resources called
 NriPluginDeployment. When NriPluginDeployment object is created, reconciliation loops kicks off and installs the
 nri-plugin specified in the NriPluginDeployment.
