 It requires zero configuration effort leaving behind the hassle of opening ports, complex firewall rules, VPN gateways, and so forth.
 
-NetBird creates an overlay peer-to-peer network connecting machines automatically regardless of their location (home, office, datacenter, container, cloud or edge environments) unifying virtual private network management experience.
+NetBird uses [NAT traversal techniques](https://en.wikipedia.org/wiki/Interactive_Connectivity_Establishment) to automatically create an overlay peer-to-peer network connecting machines regardless of location (home, office, data center, container, cloud, or edge environments), unifying virtual private network management experience.
 
 **Key features:**
-* Automatic IP allocation and management.
-* Automatic WireGuard peer (machine) discovery and configuration.
-* Encrypted peer-to-peer connections without a central VPN gateway.
-* Connection relay fallback in case a peer-to-peer connection is not possible.
-* Network management layer with a neat Web UI panel ([separate repo](https://github.com/netbirdio/dashboard))
-* Desktop client applications for Linux, MacOS, and Windows.
-* Multiuser support - sharing network between multiple users.
-* SSO and MFA support. 
-* Multicloud and hybrid-cloud support.
-* Kernel WireGuard usage when possible.
-* Access Controls - groups & rules (coming soon).
-* Private DNS (coming soon).
-* Mobile clients (coming soon).
-* Network Activity Monitoring (coming soon).

 ### A bit on NetBird internals
-* Every machine in the network runs [NetBird Agent (or Client)](client/) that manages WireGuard.
-* NetBird features [Management Service](management/) that holds network state, manages peer IPs, and distributes network updates to peers.
-* Every agent is connected to Management Service.
-* NetBird agent uses WebRTC ICE implemented in [pion/ice library](https://github.com/pion/ice) to discover connection candidates when establishing a peer-to-peer connection between machines.
-* Connection candidates are discovered with a help of [STUN](https://en.wikipedia.org/wiki/STUN) server. 
-* Agents negotiate a connection through [Signal Service](signal/) passing p2p encrypted messages.
-* Signal Service uses public WireGuard keys to route messages between peers.
-* Sometimes the NAT traversal is unsuccessful due to strict NATs (e.g. mobile carrier-grade NAT) and p2p connection isn't possible. When this occurs the system falls back to a relay server called [TURN](https://en.wikipedia.org/wiki/Traversal_Using_Relays_around_NAT), and a secure WireGuard tunnel is established via the TURN server.

 ### Testimonials
 We use open-source technologies like [WireGuard®](https://www.wireguard.com/), [Pion ICE (WebRTC)](https://github.com/pion/ice), and [Coturn](https://github.com/coturn/coturn). We very much appreciate the work these guys are doing and we'd greatly appreciate if you could support them in any way (e.g. giving a star or a contribution).

-### About Netbird
-
-Netbird is an open-source VPN platform built on top of [WireGuard®](https://www.wireguard.com/) making it easy to create secure private networks for your organization or home.
-
-It requires zero configuration effort leaving behind the hassle of opening ports, complex firewall rules, vpn gateways, and so forth.
-
-There is no centralized VPN server with Netbird - your computers, devices, machines, and servers connect to each other directly over a fast encrypted tunnel.
-
-It literally takes less than 5 minutes to provision a secure peer-to-peer VPN with Netbird. Check our [Quickstart Guide Video](https://www.youtube.com/watch?v=cWTsGUJAUaU) to see the setup in action.
-
-### Why Wireguard with Netbird?
-
-WireGuard is a modern and extremely fast VPN tunnel utilizing state-of-the-art [cryptography](https://www.wireguard.com/protocol/)
-and Netbird uses Wireguard to establish a secure tunnel between machines.
-
-Built with simplicity in mind, Wireguard ensures that traffic between two machines is encrypted and flowing, however, it requires a few things to be done beforehand.
-
-First, in order to connect, the machines have to be configured.
-On each machine, you need to generate private and public keys and prepare a WireGuard configuration file.
-The configuration also includes a private IP address that should be unique per machine.
-
-Secondly, to accept the incoming traffic, the machines have to trust each other.
-The generated public keys have to be pre-shared on the machines.
-This works similarly to SSH with its authorised_keys file.
-
-Lastly, the connectivity between the machines has to be ensured.
-To make machines reach one another, you are required to set a WireGuard endpoint property which indicates the IP address and port of the remote machine to connect to.
-On many occasions, machines are hidden behind firewalls and NAT devices,
-meaning that you may need to configure a port forwarding or open holes in your firewall to ensure the machines are reachable.
-
-The undertakings mentioned above might not be complicated if you have just a few machines, but the complexity grows as the number of machines increases.
-
-Netbird simplifies the setup by automatically generating private and public keys, assigning unique private IP addresses, and takes care of sharing public keys between the machines.
-It is worth mentioning that the private key never leaves the machine.
-So only the machine that owns the key can decrypt traffic addressed to it.
-The same applies also to the relayed traffic mentioned below.
-
-Furthermore, Netbird ensures connectivity by leveraging advanced [NAT traversal techniques](https://en.wikipedia.org/wiki/NAT_traversal)
-and removing the necessity of port forwarding, opening holes in the firewall, and having a public static IP address.  
-In cases when a direct peer-to-peer connection isn't possible, all traffic is relayed securely between peers.
-Netbird also monitors the connection health and restarts broken connections.
-
-There are a few more things that we are working on to make secure private networks simple. A few examples are ACLs, MFA and activity monitoring.
-
-Check out the WireGuard [Quick Start](https://www.wireguard.com/quickstart/) guide to learn more about configuring "plain" WireGuard without Netbird.
-
-### Netbird vs. Traditional VPN
-
-In the traditional VPN model, everything converges on a centralized, protected network where all the clients are connecting to a central VPN server.
-
-An increasing amount of connections can easily overload the VPN server.
-Even a short downtime of a server can cause expensive system disruptions, and a remote team's inability to work.
-
-Centralized VPNs imply all the traffic going through the central server causing network delays and increased traffic usage.
-
-Such systems require an experienced team to set up and maintain.
-Configuring firewalls, setting up NATs, SSO integration, and managing access control lists can be a nightmare.
-
-Traditional centralized VPNs are often compared to a [castle-and-moat](https://en.wikipedia.org/wiki/Moat) model
-in which once accessed, user is trusted and can access critical infrastructure and resources without any restrictions.
-
-Netbird decentralizes networks using direct point-to-point connections, as opposed to traditional models.
-Consequently, network performance is increased since traffic flows directly between the machines bypassing VPN servers or gateways.
-To achieve this, Netbird client applications employ signalling servers to find other machines and negotiate connections.
-These are similar to the signaling servers used in [WebRTC](https://developer.mozilla.org/en-US/docs/Web/API/WebRTC_API/Signaling_and_video_calling#the_signaling_server)
-
-Thanks to [NAT traversal techniques](https://en.wikipedia.org/wiki/NAT_traversal),
-outlined in the [Why not just Wireguard?](#why-wireguard-with-netbird) section above,
-Netbird installation doesn't require complex network and firewall configuration.
-It just works, minimising the maintenance effort.
-
-Finally, each machine or device in the Netbird network verifies incoming connections accepting only the trusted ones.
-This is ensured by Wireguard's [Crypto Routing concept](https://www.wireguard.com/#cryptokey-routing).
-
-### High-level technology overview
-In essence, Netbird 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 align="center">
-    <img src="media/high-level-dia.png" alt="high-level-dia" width="781"/>

-
-Netbird 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/netbirdio/netbird) developed by Netbird authors to make it all work together.
-
-To learn more about Netbird architecture, please refer to the [architecture section](../docs/architecture.md).
-
-### Getting Started
-
-There are 2 ways of getting started with Netbird:
-- use Cloud Managed version
-- self-hosting
-
-We recommend starting with the cloud managed version hosted at [app.netbird.io](https://app.netbird.io) - 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).

-Step-by-step video guide on YouTube:
-
-[![IMAGE ALT TEXT](https://img.youtube.com/vi/cWTsGUJAUaU/0.jpg)](https://youtu.be/cWTsGUJAUaU "Netbird - 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://app.netbird.io/](https://app.netbird.io/)
-
-    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.

-### Self-hosting
-Netbird is an open-source platform that can be self-hosted on your servers.
-
-It relies on components developed by Netbird Authors [Management Service](https://github.com/netbirdio/netbird/tree/main/management), [Management UI Dashboard](https://github.com/netbirdio/dashboard), [Signal Service](https://github.com/netbirdio/netbird/tree/main/signal), 
-a 3rd party open-source STUN/TURN service [Coturn](https://github.com/coturn/coturn) and a 3rd party service [Auth0](https://auth0.com/).
-
-All the components can be self-hosted except for the Auth0 service.
-We chose Auth0 to "outsource" the user management part of the platform because we believe that implementing a proper user auth requires significant amount of time to make it right. 
-We focused on connectivity instead. It also offers an always free plan that should be ok for most users as its limits are high enough for most teams.
-
-If you would like to learn more about the architecture please refer to the [Netbird Architecture section](architecture.md).

-[![IMAGE ALT TEXT](https://img.youtube.com/vi/Ofpgx5WhT0k/0.jpg)](https://youtu.be/Ofpgx5WhT0k "Netbird Self-Hosting Guide")
-
-### Requirements
-
-- Virtual machine offered by any cloud provider (e.g., AWS, DigitalOcean, Hetzner, Google Cloud, Azure ...). 
-- Any Unix OS.
-- Docker Compose installed (see [Install Docker Compose](https://docs.docker.com/compose/install/)).
-- Domain name pointing to the public IP address of your server.
-- Netbird Open ports ```443, 33071, 33073, 10000``` (Dashboard, Management HTTP API, Management gRpc API, Signal gRpc) on your server. 
-- Coturn is used for relay using the STUN/TURN protocols. It requires a listening port, ```UDP 3478```,  and range of ports,```UDP 49152-65535```, for dynamic relay connections. These are set as defaults in [setup file](https://github.com/netbirdio/netbird/blob/main/infrastructure_files/setup.env#L34), but can be configured to your requirements. 
-- Maybe a cup of coffee or tea :)
-
-### Step-by-step guide
-
-For this tutorial we will be using domain ```test.netbird.io``` which points to our Ubuntu 20.04 machine hosted at Hetzner.
-
-1. Create Auth0 account at [auth0.com](https://auth0.com/).
-2. Login to your server, clone Netbird repository:
-   
-   ```bash 
-   git clone https://github.com/netbirdio/netbird.git netbird/
-   ```
-   
-   and switch to the ```netbird/infrastructure_files/``` folder that contains docker compose file:
-   
-   ```bash 
-   cd netbird/infrastructure_files/
-   ```
-3. Prepare configuration files.
-   
-   To simplify the setup we have prepared a script to substitute required properties in the [turnserver.conf.tmpl](../infrastructure_files/turnserver.conf.tmpl),[docker-compose.yml.tmpl](../infrastructure_files/docker-compose.yml.tmpl) and [management.json.tmpl](../infrastructure_files/management.json.tmpl) files.
-   
-   The [setup.env](../infrastructure_files/setup.env) file contains the following properties that have to be filled:
-   
-   ```bash
-   # Dashboard domain. e.g. app.mydomain.com
-   NETBIRD_DOMAIN=""
-   # e.g. dev-24vkclam.us.auth0.com
-   NETBIRD_AUTH0_DOMAIN=""
-   # e.g. 61u3JMXRO0oOevc7gCkZLCwePQvT4lL0
-   NETBIRD_AUTH0_CLIENT_ID=""
-   # e.g. https://app.mydomain.com/ or https://app.mydomain.com,
-   # Make sure you used the exact same value for Identifier
-   # you used when creating your Auth0 API
-   NETBIRD_AUTH0_AUDIENCE=""
-   # e.g. hello@mydomain.com
-   NETBIRD_LETSENCRYPT_EMAIL=""
-   ```
-   > Other options are available, but they are automatically updated.
-   
-   Please follow the steps to get the values. 
-
-4. Configure ```NETBIRD_AUTH0_DOMAIN``` ```NETBIRD_AUTH0_CLIENT_ID``` ```NETBIRD_AUTH0_AUDIENCE``` properties.          
-   
-   * To obtain these, please use [Auth0 React SDK Guide](https://auth0.com/docs/quickstart/spa/react/01-login#configure-auth0) up until "Install the Auth0 React SDK".
-   
-      :grey_exclamation: Use ```https://YOUR DOMAIN``` as ````Allowed Callback URLs````, ```Allowed Logout URLs```, ```Allowed Web Origins``` and ```Allowed Origins (CORS)```
-   * set the variables in the ```setup.env```
-5. Configure ```NETBIRD_AUTH0_AUDIENCE``` property. 
-   
-   * Check [Auth0 Golang API Guide](https://auth0.com/docs/quickstart/backend/golang) to obtain AuthAudience.
-   * set the property in the ```setup.env``` file.
-6. Configure ```NETBIRD_LETSENCRYPT_EMAIL``` property.
-   
-   This can be any email address. [Let's Encrypt](https://letsencrypt.org/) will create an account while generating a new certificate.    
-
-7. Make sure all the properties set in the ```setup.env``` file and run: 
-   
-    ```bash
-    ./configure.sh
-    ```
-   
-   This will export all the properties as environment variables and generate ```docker-compose.yml``` and ```management.json``` files substituting required variables.
-
-8. Run docker compose:
-
-   ```bash
-   docker-compose up -d
-   ```
-9. Optionally check the logs by running: 
-        
-    ```bash
-    docker-compose logs signal
-    docker-compose logs management
-    docker-compose logs coturn
-    docker-compose logs dashboard
-
-10. Once the server is running, you can access the dashboard by https://$NETBIRD_DOMAIN
-11. Adding a peer will require you to enter the management URL by following the steps in the page https://$NETBIRD_DOMAIN/add-peer and in the 3rd step:
-```shell
-sudo netbird up --setup-key <PASTE-SETUP-KEY> --management-url https://$NETBIRD_DOMAIN:33073
-```
