+description: Pantheon private network quickstart on Azure tutorial
+<!--- END of page meta data -->
+
+# Azure Private Network Quickstart tutorial
+
+This tutorial describes how to use the [Pantheon quickstart](https://github.com/PegaSysEng/pantheon-quickstart) 
+to run a private network of Pantheon nodes in a Docker container in a Linux Virtual 
+machine hosted on Microsoft Azure.
+
+## Requirements
+
+* An azure account. A [free trial account](https://azure.microsoft.com/en-us/free/) will work for this tutorial.
+* Be able to conne t to a remote console using SSH. If you use Linux or macOS, you already have one 
+integrated, otherwise you can try tools like [Putty](https://www.putty.org/) (free; open-source), 
+[mRemoteNG](https://mremoteng.org/) (free; open-source), 
+[Terminals](https://github.com/terminals-Origin/Terminals) (free; open-source)
+or [MobaXterm](https://mobaxterm.mobatek.net/) (free; paid Pro version available).
+
+## Connect to Azure Portal
+Log in to [Azure portal](https://portal.azure.com/) using your account credentials.
+
+## Creating resources
+On the home page, click on ![Create resource button](create-resource-button-screenshot.png)
+at the top left hand corner.
+
+Search the Marketplace for **Ubuntu Server 18.04 LTS** by Canonical and click on it. 
+An information page is displayed. Accept the default deployment model of Resource Manager and click **Create**.
+
+In **Create a virtual machine**, set the following values for each tab as follows::
+
+### Basics step
+  * Subscription --> free trial
+  * Resource group --> create a new one and call it as you like, "pantheon-quickstart" may be a good name.
+  * Virtual machine name --> quickstart
+  * Region --> **Central US** will probably selected by default, don't bother changing it.
+  * Availability options --> No infrastructure redundancy required
+  * Image --> Ubuntu Server 18.04 LTS
+  * Size --> You can keep the proposed hosting plan size as this quickstart won't require a lot 
+  of power and disk space. A **Standard D2s v3 (2 vcpus, 8 GB memory)** will do the job and will be 
+  less expensive.
+  * Authentication type --> choose the one you prefer, as this is not a critical machine, you can just
+  use a password, but a SSH public key is nice too and simpler if you have one.
+  * Username --> provide a user name, here we propose **azure** as a user name and we'll use it all 
+  along this tutorial.
+  * Depending on the authentication method you chose, either fill the password or the public key.
+  * Login with Azure Acrive Directory --> keep it **off**
+  * Public inbound ports --> Allow selected ports
+  * Select inbound ports --> select **HTTP** and **SSH**
+  
+Then go up on the top of the page and switch to the **Guest config** step tab.
+
+### Guest config
+This step aims at installing required software (Docker and Docker-compose) on your virtual machine 
+and retrieve and run the quickstart private network.
+
+To do so, click on the link named **Select an extension to install** and a new resource pane will
+appear on the right.
+
+In the list click on **Custom Script For Linux**, another pane opens with a blue **Create** button at
+its bottom, click on it.
+
+A form with only two fields appear:
+
+First open another browser tab or window with [https://raw.githubusercontent.com/PegaSysEng/pantheon-quickstart/master/azure/install_and_run.sh](https://raw.githubusercontent.com/PegaSysEng/pantheon-quickstart/master/azure/install_and_run.sh)
+
+Save (++ctrl+s++) this script to your computer, anywhere you like, as install_and_run.sh. 
+
+Then click on the **Script files** field, and once the file browsing dialog appear, select the `install_and_run.sh` 
+you just saved.
+
+Fill the second field named **Command** with the following informations (replacing the pre filled `sh script.sh`):
+
+```bash
+sh install_and_run.sh azure
+```
+
+!!!important
+    The username is included at the end of this command, **azure** in our case, but change
+    to whatever you defined on the Basics step if you did not use the same as us.
+    
+Then click **Ok** and then on the **Review + create** blue button at the bottom.
+
+Then once everything is ok (a green **Validation passed** message should show on the top of the screen), 
+press the blue **Create** button.
+
+You should see a **Your deployment is underway** screen with all the resources creating. It takes
+some time, around 5mn, so be patient and have a nice :tea: or :coffee:.
+
+Once the deployment is done, you should see **Your deployment is complete** and a list of all the
+deployed resources with green check-marks.
+
+![Your deployment is complete screenshot](deployment-complete-screenshot.png)
+
+CLick on the resource named **quickstart** in this list and you'll land on the virtual
+machine overview page.
+
+## Accessing the Alethio EthStat-light explorer
+
+On the right part of the virtual machine page you can read the **Public IP address** of this machine. 
+Copy it then open a new browser tab or window and past it in the navigation bar.
+
+You now should see the the EthStat-light explorer.
+Wait a few seconds and you should see 6 peers indicated and a few blocks mined.
+

+
+## Rpc enpoints
+
+For the following tutorial steps, you will have to know that your RPC endpoints are the
+following :
+
+* for the HTTP RPC endpoint: **http://&lt;your VM public IP>/jsonrpc**
+* for the Web Socket RPC endpoint: **ws://&lt;your VM public IP>/jsonws**
+
+You can now follow the quickstart tutorial starting from 
+[the part where we show how to create RPC requests](../Private-Network-Quickstart.md#run-json-rpc-requests).
+
+## Shutting down the quickstart
+
+!!!attention
+    Don't forget to shutdown the quickstart it you don't need it as it will consume your Azure resources
+    and that can be expensive of at least drain your free credits from your free trial account.
+
+You have multiple ways to shutdown the quickstart depending on if you want to restart it
+from scratch after that or continue using the same installation. Here are the options:
+
+### I want to remove everything from my Azure account.
+
+This is the only way to be sure your Azure resources won't consume any credits.
+
+To do so, simply navigate in the Azure portal to your resource group, the one we named **pantheon-quickstart**
+then click on the **Delete resource group** button.
+
+### I want to remove the virtual machine only.
+Then simply navigate in the Azure portal to your resource group, the one we named **pantheon-quickstart**
+then click on the virtual machine resource and click the **Delete** button.
+
+### I want to keep the VM but remove the nodes network.
+Navigate to the VM in your Azure portal (click on **All services** in the left pane, then on 
+**Virtual machines** and click on the one you named **quickstart**) and click the **connect** 
+button that will give you the information to connect with SSH (see [Requirements](#requirements)).
+
+Once connected to the machine, navigate to the pantheon-quickstart directory:
+```bash
+cd pantheon-quickstart
+``` 
+then run the remove script
+```bash
+./remove.sh
+```
+
+If you want to run the network again, then you can use the following script:
+```bash
+./run.sh -p 80
+```
+
+Where 80 is the port number to use for Block Explorer and RPC connections.
+ 
+### I just want to stop the nodes network and be able to resume it.
+Connect to the VM using SSH like for "[I want to keep the VM but remove the nodes network.](#i-want-to-keep-the-vm-but-remove-the-nodes-network)"
+but instead of running the remove script, run the stop script.
+```bash
+./stop.sh
+```
+you will be then able to resume the network with
+```bash
+./resume.sh
+```
