 ## How to become a contributor and submit your own code
 
-### Environment setup
-
-It is recommended to use filter to manage the GitHub email notification, see [examples for setting filters to Kubernetes Github notifications](https://github.com/kubernetes/community/blob/master/communication/best-practices.md#examples-for-setting-filters-to-kubernetes-github-notifications)
-
-To install development dependencies you can set up a python virtual env with the necessary dependencies:
-
-```ShellSession
-virtualenv venv
-source venv/bin/activate
-pip install -r tests/requirements.txt
-```
-
-#### Linting
-
-Kubespray uses [pre-commit](https://pre-commit.com) hook configuration to run several linters, please install this tool and use it to run validation tests before submitting a PR.
-
-```ShellSession
-pre-commit install
-pre-commit run -a  # To run pre-commit hook on all files in the repository, even if they were not modified
-```
-
-#### Molecule
-
-[molecule](https://github.com/ansible-community/molecule) is designed to help the development and testing of Ansible roles. In Kubespray you can run it all for all roles with `./tests/scripts/molecule_run.sh` or for a specific role (that you are working with) with `molecule test` from the role directory (`cd roles/my-role`).
-
-When developing or debugging a role it can be useful to run `molecule create` and `molecule converge` separately. Then you can use `molecule login` to SSH into the test environment.
-
-#### Vagrant
-
-Vagrant with VirtualBox or libvirt driver helps you to quickly spin test clusters to test things end to end. See [README.md#vagrant](README.md)
-
 ### Contributing A Patch
 
 1. Submit an issue describing your proposed change to the repo in question.
 2. The [repo owners](OWNERS) will respond to your issue promptly.
 3. Fork the desired repo, develop and test your code changes.
-4. Install [pre-commit](https://pre-commit.com) and install it in your development repo.
-5. Addess any pre-commit validation failures.
-6. Sign the CNCF CLA (<https://git.k8s.io/community/CLA.md#the-contributor-license-agreement>)
-7. Submit a pull request.
-8. Work with the reviewers on their suggestions.
-9. Ensure to rebase to the HEAD of your target branch and squash un-necessary commits (<https://blog.carbonfive.com/always-squash-and-rebase-your-git-commits/>) before final merger of your contribution.
+4. Sign the CNCF CLA (https://git.k8s.io/community/CLA.md#the-contributor-license-agreement)
+5. Submit a pull request.

+    ansible-playbook -i inventory/mycluster/hosts.yml --become --become-user=root cluster.yml
 
 Note: When Ansible is already installed via system packages on the control machine, other python packages installed via `sudo pip install -r requirements.txt` will go to a different directory tree (e.g. `/usr/local/lib/python2.7/dist-packages` on Ubuntu) from Ansible's (e.g. `/usr/lib/python2.7/dist-packages/ansible` still on Ubuntu).
 As a consequence, `ansible-playbook` command will fail with:
-
-```raw
+```
 ERROR! no action detected in task. This often indicates a misspelled module name, or incorrect module path.
 ```
-
-probably pointing on a task depending on a module present in requirements.txt.
+probably pointing on a task depending on a module present in requirements.txt (i.e. "unseal vault").
 
 One way of solving this would be to uninstall the Ansible package and then, to install it via pip but it is not always possible.
 A workaround consists of setting `ANSIBLE_LIBRARY` and `ANSIBLE_MODULE_UTILS` environment variables respectively to the `ansible/modules` and `ansible/module_utils` subdirectories of pip packages installation location, which can be found in the Location field of the output of `pip show [package]` before executing `ansible-playbook`.
 
-A simple way to ensure you get all the correct version of Ansible is to use the [pre-built docker image from Quay](https://quay.io/repository/kubespray/kubespray?tab=tags).
-You will then need to use [bind mounts](https://docs.docker.com/storage/bind-mounts/) to get the inventory and ssh key into the container, like this:
-
-```ShellSession
-git checkout v2.20.0
-docker pull quay.io/kubespray/kubespray:v2.20.0
-docker run --rm -it --mount type=bind,source="$(pwd)"/inventory/sample,dst=/inventory \
-  --mount type=bind,source="${HOME}"/.ssh/id_rsa,dst=/root/.ssh/id_rsa \
-  quay.io/kubespray/kubespray:v2.20.0 bash
-# Inside the container you may now run the kubespray playbooks:
-ansible-playbook -i /inventory/inventory.ini --private-key /root/.ssh/id_rsa cluster.yml
-```
-
 ### Vagrant
 
 For Vagrant we need to install python dependencies for provisioning tasks.
 Check if Python and pip are installed:
 
-```ShellSession
-python -V && pip -V
-```
+    python -V && pip -V
 
 If this returns the version of the software, you're good to go. If not, download and install Python from here <https://www.python.org/downloads/source/>
+Install the necessary requirements
 
-Install Ansible according to [Ansible installation guide](/docs/ansible.md#installing-ansible)
-then run the following step:
+    sudo pip install -r requirements.txt
+    vagrant up
 
-```ShellSession
-vagrant up

-## Container Runtime Notes
+Note: The list of validated [docker versions](https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG-1.13.md) was updated to 1.11.1, 1.12.1, 1.13.1, 17.03, 17.06, 17.09, 18.06. kubeadm now properly recognizes Docker 18.09.0 and newer, but still treats 18.06 as the default supported version. The kubelet might break on docker's non-standard version numbering (it no longer uses semantic versioning). To ensure auto-updates don't break your cluster look into e.g. yum versionlock plugin or apt pin).
 
-- The list of available docker version is 18.09, 19.03 and 20.10. The recommended docker version is 20.10. The kubelet might break on docker's non-standard version numbering (it no longer uses semantic versioning). To ensure auto-updates don't break your cluster look into e.g. yum versionlock plugin or apt pin).

+  [semver](http://semver.org/). Every version describes only a stable release.
   Breaking changes, if any introduced by changed defaults or non-contrib ansible roles'
   playbooks, shall be described in the release notes. Other breaking changes, if any in

   considered out of Kubespray scope and are up to the components' teams to deal with and
   document.
 
-* Minor releases can change components' versions, but not the major `kube_version`.
-  Greater `kube_version` requires a new major or minor release. For example, if Kubespray v2.0.0

-## Release note creation
-
-You can create a release note with:
-
-```shell
-export GITHUB_TOKEN=<your-github-token>
-export ORG=kubernetes-sigs
-export REPO=kubespray
-release-notes --start-sha <The start commit-id> --end-sha <The end commit-id> --dependencies=false --output=/tmp/kubespray-release-note --required-author=""
-```
-
-If the release note file(/tmp/kubespray-release-note) contains "### Uncategorized" pull requests, those pull requests don't have a valid kind label(`kind/feature`, etc.).
-It is necessary to put a valid label on each pull request and run the above release-notes command again to get a better release note)
-
-## Container image creation
-
-The container image `quay.io/kubespray/kubespray:vX.Y.Z` can be created from Dockerfile of the kubespray root directory:
-
-```shell
-cd kubespray/
-nerdctl build -t quay.io/kubespray/kubespray:vX.Y.Z .
-nerdctl push quay.io/kubespray/kubespray:vX.Y.Z
-```
-
-The container image `quay.io/kubespray/vagrant:vX.Y.Z` can be created from build.sh of test-infra/vagrant-docker/:
-
-```shell
-cd kubespray/test-infra/vagrant-docker/
-./build vX.Y.Z
-```
-
-Please note that the above operation requires the permission to push container images into quay.io/kubespray/.
-If you don't have the permission, please ask it on the #kubespray-dev channel.
+  And Kubespray v3.x.x shall be bound to ``kube_version: 2.x.x`` respectively.

+# Deploy MetalLB into Kubespray/Kubernetes
+```
+MetalLB hooks into your Kubernetes cluster, and provides a network load-balancer implementation. In short, it allows you to create Kubernetes services of type “LoadBalancer” in clusters that don’t run on a cloud provider, and thus cannot simply hook into paid products to provide load-balancers.
+```
+This playbook aims to automate [this](https://metallb.universe.tf/tutorial/layer2/tutorial). It deploys MetalLB into kubernetes and sets up a layer 2 loadbalancer.

+## Install

 # Deploy Heketi/Glusterfs into Kubespray/Kubernetes
-
 This playbook aims to automate [this](https://github.com/heketi/heketi/blob/master/docs/admin/install-kubernetes.md) tutorial. It deploys heketi/glusterfs into kubernetes and sets up a storageclass.
 
-## Important notice
-
-> Due to resource limits on the current project maintainers and general lack of contributions we are considering placing Heketi into a [near-maintenance mode](https://github.com/heketi/heketi#important-notice)
-
 ## Client Setup
-
 Heketi provides a CLI that provides users with a means to administer the deployment and configuration of GlusterFS in Kubernetes. [Download and install the heketi-cli](https://github.com/heketi/heketi/releases) on your client machine.
 
 ## Install
-
 Copy the inventory.yml.sample over to inventory/sample/k8s_heketi_inventory.yml and change it according to your setup.
-
-```shell
+```
 ansible-playbook --ask-become -i inventory/sample/k8s_heketi_inventory.yml contrib/network-storage/heketi/heketi.yml
 ```
 
 ## Tear down
-
-```shell
+```
 ansible-playbook --ask-become -i inventory/sample/k8s_heketi_inventory.yml contrib/network-storage/heketi/heketi-tear-down.yml
 ```
