 ## What's the Jenkins Operator?
 
-Jenkins operator is a Kubernetes native operator which fully manages Jenkins on Kubernetes.
-It was built with immutability and declarative configuration as code in mind.
+The Jenkins Operator is a [Kubernetes Native Operator](https://kubernetes.io/docs/concepts/extend-kubernetes/operator/) which manages operations for Jenkins on Kubernetes.
+It has been built with Immutability and declarative Configuration as Code in mind.
 
-Out of the box it provides:
-- integration with Kubernetes ([Jenkins kubernetes-plugin](https://github.com/jenkinsci/kubernetes-plugin))
-- pipelines as code ([Jenkins pipelines](https://jenkins.io/doc/book/pipeline/))
-- extensibility via groovy scripts (similar to [Jenkins script console](https://wiki.jenkins.io/display/JENKINS/Jenkins+Script+Console)) or ([configuration as code plugin](https://github.com/jenkinsci/configuration-as-code-plugin))
-- secure defaults and hardening (see [the security section](https://jenkinsci.github.io/kubernetes-operator/docs/security/) of the documentation)
+
+## Preliminaries
+
+Considering that this Operator is created for managing instances for Jenkins, 
+it is important to understand what 
+- [Jenkins Pipelines](https://jenkins.io/doc/book/pipeline/) and 
+- CasC ([Configuration as Code](https://github.com/jenkinsci/configuration-as-code-plugin)) are.
+
+Jenkins Pipelines use Scripts written in [Groovy](https://groovy-lang.org/) which aid in the CasC aspect of Jenkins.
+
+Jenkins uses [plugins](https://plugins.jenkins.io/) like CasC to extend it's solution space by carrying out Jobs of different kinds and providing a composable infrastructure for your CI/CD.

+# Security Policy
+
+The Jenkins project takes security seriously.
+We make every possible effort to ensure users can adequately secure their automation infrastructure.
+To that end, we work with Jenkins core and plugin developers, as well as security researchers, to fix security vulnerabilities in Jenkins in a timely manner, and to improve the security of Jenkins in general.
+
+## Reporting Security Vulnerabilities
+
+Please report security vulnerabilities in the Jenkins issue tracker under the [SECURITY project](https://issues.jenkins-ci.org/browse/SECURITY).
+This project is configured in such a way that only the reporter and the security team can see the details.
+By restricting access to this potentially sensitive information, we can work on a fix and deliver it before the method of attack becomes well-known.
+
+If you are unable to report using our issue tracker, you can also send your report to the private Jenkins security team mailing list: `jenkinsci-cert@googlegroups.com`
+
+The Jenkins security team will then file an issue on your behalf, and will work with the maintainers of the affected component(s) to get the issue resolved.

+Getting support for Jenkins
+===========================
+
+Jenkins is a community-driven project, and it does not provide user support in the common meaning.
+Nevertheless, there is an active community which might be able to help with the issues you experience.
+The [Jenkins JIRA](https://issues.jenkins-ci.org/secure/Dashboard.jspa) is **NOT** a support site. 
+If you need assistance or have general questions, visit us in [chat](https://jenkins.io/chat/), or email one of the user [mailing lists](https://jenkins.io/mailing-lists/).
+Also check out the main component's page for specific communication channel references.
+
+Please be aware that most Jenkins components are maintained by volunteers. 
+This means there is no guarantee of a timely response or issue resolution.
+If you want commercial support for Jenkins,
+there are companies which offer it.
+See the list on [this Wiki page](https://wiki.jenkins.io/display/JENKINS/Commercial+Support).
+Note that this list should not be viewed as endorsement by the Jenkins project, the list is provided for reference.
