 ## 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 use `pip install -r tests/requirements.txt`
-
-#### Linting
-
-Kubespray uses `yamllint` and `ansible-lint`. To run them locally use `yamllint .` and `./tests/scripts/ansible-lint.sh`
-
-#### 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)
-

+# 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

-##### k8s_nodes
-Allows a custom defintion of worker nodes giving the operator full control over individual node flavor and
-availability zone placement. To enable the use of this mode set the `number_of_k8s_nodes` and
-`number_of_k8s_nodes_no_floating_ip` variables to 0. Then define your desired worker node configuration
-using the `k8s_nodes` variable.
-
-For example:
-```
-k8s_nodes = {
-  "1" = {
-    "az" = "sto1"
-    "flavor" = "83d8b44a-26a0-4f02-a981-079446926445"
-    "floating_ip" = true
-  },
-  "2" = {
-    "az" = "sto2"
-    "flavor" = "83d8b44a-26a0-4f02-a981-079446926445"
-    "floating_ip" = true
-  },
-  "3" = {
-    "az" = "sto3"

-    "floating_ip" = true
-  }
-}
-```
-
-Would result in the same configuration as:
-```

-flavor_k8s_node = "83d8b44a-26a0-4f02-a981-079446926445"
