-OpenNebula manages workloads based on KVM, LXC system containers. It can manage both single VMs and complex mult-tier services composed of several VMs that require sophisticated elasticity rules and dynamic adaptability. In OpenNebula, VM-based applications are created from images and templates. Users can modify templates or create new ones; they can be shared by the cloud administrator using a private corporate marketplace. Pre-defined, fully-functional templates are also available in the OpenNebula Marketplace, which allows users to easily download and deploy VMs, virtual appliances and full-featured mult-VM services.

 Next Steps

 **Building an evaluation environment**
 
-You can always evaluate OpenNebula by following our `Quick Start <http://docs.opennebula.io/6.4/quick_start/index.html>`_ guide, where you will learn how to use `vOneCloud <http://docs.opennebula.io/6.4/quick_start/deployment_basics/try_opennebula_on_vmware.html>`_—our virtual appliance for VMware vSphere—or `miniONE <http://docs.opennebula.io/6.4/quick_start/deployment_basics/try_opennebula_on_kvm.html>`_—our deployment tool for installing a single-node OpenNebula cloud with KVM inside a virtual machine or physical host— and then to provision an OpenNebula Edge Cluster on AWS to run your `containers <http://docs.opennebula.io/6.4/quick_start/usage_basics/running_containers.html>`_, `virtual machines <http://docs.opennebula.io/6.4/quick_start/usage_basics/running_virtual_machines.html>`_ or `Kubernetes <http://docs.opennebula.io/6.4/quick_start/usage_basics/running_kubernetes_clusters.html>`_ clusters on a truly multi-cloud environment. This is the fastest way for you to familiarize yourself with the new OpenNebula, as you only need the necessary resources to deploy the OpenNebula front-end.
+We strongly recommend you evaluate OpenNebula by following our :ref:`Quick Start Guide <quick_start>`. The Guide will walk you through a set of tutorials that start at :ref:`installing an OpenNebula Front-end <try_opennebula_on_kvm>`, continue with :ref:`deploying an Edge Cluster on AWS <first_edge_cluster>`, then a :ref:`WordPress appliance <running_virtual_machines>` and finally a :ref:`Kubernetes cluster <running_kubernetes_clusters>`, all using the Sunstone web UI. This is the quickest way to familiarize yourself with OpenNebula since most tutorials take under ten minutes to complete.
 
 **Setting up a production environment**
 
-If you are interested in building a production environment, the `Cloud Architecture Design <http://docs.opennebula.io/6.4/overview/cloud_architecture_and_design/cloud_architecture_design.html>`_ guide is a good resource for you to explore the different options to consider and the available choices. Remember that if you need our support at any time, or access to our professional services (including our **Managed Cloud Services**) or to the **Enterprise Edition**, you can always `contact us <https://opennebula.io/enterprise>`_.
