 Deploy OpenNebula Front-end on AWS
 ==================================
 
-In this guide, we'll go through a Front-end OpenNebula environment deployment, where all the OpenNebula services needed to use, manage and run the cloud will be collocated on a single dedicated bare-metal server or virtual machine. You will be also able to deploy a local KVM node within the same single server or virtual machine to try out OpenNebula, or for daily development work. Afterwards, if you need more resources or want to try out the automatic provisioning features for building multi-provider hybrid clouds, you can continue to the :ref:`Operations Guide <operation_basics>` to add a remote Edge Cluster based on KVM using AWS bare-metal instances to your shiny new OpenNebula cloud!
+In this guide, we'll go through a Front-end OpenNebula environment deployment, where all the OpenNebula services needed to use, manage and run the cloud will be collocated on a single dedicated bare-metal server or Virtual Machine (VM). You will be also able to deploy a local KVM node within the same single server or VM to try out OpenNebula, or for daily development work. Afterwards, if you need more physical resources or want to try out the automatic provisioning features for building multi-provider hybrid clouds, you can continue to the :ref:`Operations Guide <operation_basics>` to add a remote Edge Cluster based on KVM using AWS bare-metal instances to your shiny new OpenNebula cloud!
 
 While all the :ref:`installation and configuration <opennebula_installation>` steps can be done manually and would give you a better insight and control over what and how it is configured, we'll focus on the most straightforward approach by leveraging the miniONE tool.
 
-The miniONE tool is a simple deployment script that deploys an OpenNebula Front-end and, optionaly, a single KVM node within a single physical or virtual machine. This tool is mainly intended for evaluation, development, and testing, but can also be used as a base for larger short-lived deployments. Usually, it takes just a few minutes to get the environment ready.
