+Setting Up a Development Environment
+=====================================
+
+This page describes how to setup a working development environment that can be used in developing stackube on Ubuntu or CentOS. These instructions assume you're already installed git, golang and python on your host.
+
+=================
+Getting the code
+=================
+
+Grab the code:
+::
+
+  git clone git://git.openstack.org/openstack/stackube
+
+==================================
+Spawn up Kubernetes and OpenStack
+==================================
+
+devstack is used to spawn up a kubernetes and openstack environment.
+
+Create stack user:
+::
+
+  sudo useradd -s /bin/bash -d /opt/stack -m stack
+  echo "stack ALL=(ALL) NOPASSWD: ALL" | sudo tee /etc/sudoers.d/stack
+  sudo su - stack
+
+Grab the devstack:
+::
+
+  git clone https://git.openstack.org/openstack-dev/devstack -b stable/ocata
+  cd devstack
+
+Create a local.conf:
+::
+
+  curl -sSL https://raw.githubusercontent.com/openstack/stackube/master/devstack/local.conf.sample -o local.conf
+
+Start installation:
+::
+
+  ./stack.sh
+
+Setup environment variables for kubectl and openstack client:
+::
+
+  export KUBECONFIG=$HOME/admin.conf
+  source openrc admin admin
+
+================
+Add a new node
+================
+
+Same procedure as above, but create the local.conf by following command:
+::
+
+  curl -sSL https://raw.githubusercontent.com/openstack/stackube/master/devstack/local.conf.node.sample -o local.conf
+
+And configure local.conf:
+
+- Set `HOST_IP` to local host's IP
+- Set `SERVICE_HOST` to master's IP
+- Set `KUBEADM_TOKEN` to kubeadm token
+
