-A Slack bot which keeps eye on your Kubernetes resources and notifies about resources life cycles events, errors and warnings. It allows you to define and run certain checks on resouces specs.
+BotKube integration with Slack or Mattermost helps you monitor your Kubernetes cluster, debug critical deployments and gives recommendations for standard practices by running checks on the Kubernetes resources.
 You can also ask BotKube to execute kubectl commands on k8s cluster which helps debugging an application or cluster.

 ## Getting started
+Please follow [this](https://www.botkube.io/installation/) for complete BotKube installation guide.
 ### Install BotKube app to your Slack workspace
 Click the "Add to Slack" button provided to install `BotKube` Slack application to your workspace. Once you authorized the application, you will be provided a BOT Access token. Kindly note down that token which will be required while deploying BotKube controller to your cluster

 - **Informer Controller:** Registers informers to kube-apiserver to watch events on the configured k8s resources. It forwards the incoming k8s event to the Event Manager
 - **Event Manager:** Extracts required fields from k8s event object and creates a new BotKube event struct. It passes BotKube event struct to the Filter Engine
 - **Filter Engine:** Takes the k8s object and BotKube event struct and runs Filters on them. Each filter runs some validations on the k8s object and modifies the messages in the BotKube event struct if required.
-- **Notifier:** Finally, notifier sends BotKube event over the configured communication channel.
-- **Slack RTM Client:** Slack RTM API authenticates and connects to the Slack messaging server. It parses and forwards the incoming message to Executer. 
-- **Executor:** Executes notifier or kubectl command and sends back the result to the RTM client.
