+## Introduction
+
+Wiretrustee is a WireGuard®-based platform that connects your devices securely into a peer-to-peer private network.
+
+It simplifies VPN creation and management for your organization without the hassle of opening ports, complex firewall rules, and so forth.
+
+It literally takes less than 5 minutes to provision a secure peer-to-peer VPN with Wiretrustee. 
+
+### High-level overview
+In essence, Wiretrustee is an open source platform consisting of a collection of systems, responsible for handling peer-to-peer connections, tunneling and network management (IP, keys, ACLs, etc).
+

+</p>
+
+Wiretrustee uses open-source technologies like [WireGuard®](https://www.wireguard.com/), [Pion ICE (WebRTC)](https://github.com/pion/ice), [Coturn](https://github.com/coturn/coturn),
+and [software](https://github.com/wiretrustee/wiretrustee) developed by Wiretrustee authors to make it all work together.
+
+To learn more about Wiretrustee architecture, please refer to the [architecture section](../docs/architecture.md).
+
+### Getting Started
+
+There are 2 ways of getting started with Wiretrustee:
+- use Cloud Managed version
+- self-hosting
+
+We recommend starting with the cloud managed version hosted at [beta.wiretrustee.com](https://beta.wiretrustee.com) - the quickest way to get familiar with the system.
+See [Quickstart Guide](../docs/quickstart.md) for instructions.
+
+If you don't want to use the managed version, check out our [Self-hosting Guide](../docs/self-hosting.md).

+## Quickstart guide (Cloud Managed version)
+Step-by-step video guide on YouTube:
+
+[![IMAGE ALT TEXT](https://img.youtube.com/vi/j0EPaK5Rapw/0.jpg)](https://youtu.be/j0EPaK5Rapw "Wiretrustee - secure private network in less than 5 minutes")
+
+This guide describes how to create secure VPN and connect 2 machines peer-to-peer.
+
+One machine is a Raspberry Pi Compute Module 4 hosted at home (Peer A), and the other one is a regular Ubuntu server running in the Data Center (Peer B).
+Both machines are running Linux (Raspbian and Ubuntu respectively), but you could also use Mac or Windows operating systems.
+
+1. Sign-up at [https://beta.wiretrustee.com/](https://beta.wiretrustee.com/peers)
+
+    You can use your email and password to sign-up or any available social login option (e.g., GitHub account)
+    
+    <img src="media/auth.png" alt="auth" width="350"/>
+
+2. After a successful login you will be redirected to the ```Peers``` screen which is empty because you don't have any peers yet.
+   
+    Click ```Add peer``` to add a new machine.
+    
+    <img src="media/empty-peers.png" alt="empty-peers" width="700"/>
+    
+3.  Choose a setup key which will be used to associate your new machine with your account (in our case it is ```Default key```).
+
+    Choose your machine operating system (in our case it is ```Linux```) and proceed with the installation steps on the machine.
+
+    <img src="media/add-peer.png" alt="add-peer" width="700"/>    
+
+4. Repeat #3 for the 2nd machine.
+5. Return to ```Peers``` and you should notice 2 new machines with status ```Connected```
+   
+    <img src="media/peers.png" alt="peers" width="700"/>
+
+6. To test the connection you could try pinging devices:
+   
+    On Peer A:
+    ```ping 100.64.0.2```
+    
+    On Peer B:
+    ```ping 100.64.0.1```
+7. Done! You now have a secure peer-to-peer VPN configured.
