+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, caste, color, religion, or sexual
+identity and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the overall
+  community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or advances of
+  any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email address,
+  without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.

-### Why using Wiretrustee?
+<br>
 
-* Connect multiple devices to each other via a secure peer-to-peer Wireguard VPN tunnel. At home, the office, or anywhere else.
-* No need to open ports and expose public IPs on the device, routers etc.
-* Uses Kernel Wireguard module if available.
-* Automatic network change detection. When a new peer joins the network others are notified and keys are exchanged automatically.  
-* Automatically reconnects in case of network failures or switches.
-* Automatic NAT traversal.
-* Relay server fallback in case of an unsuccessful peer-to-peer connection.
-* Private key never leaves your device.
-* Automatic IP address management.
-* Intuitive UI Dashboard.
-* Works on ARM devices (e.g. Raspberry Pi).
-* Open-source (including Management Service)
+**NetBird is an open-source VPN management platform built on top of WireGuard® making it easy to create secure private networks for your organization or home.**
 
-### Secure peer-to-peer VPN in minutes
-![animation](media/peers.gif)
+It requires zero configuration effort leaving behind the hassle of opening ports, complex firewall rules, VPN gateways, and so forth.
 
-### A bit on Wiretrustee internals
-* Wiretrustee features a Management Service that offers peer IP management and network updates distribution (e.g. when new peer joins the network).
-* Wiretrustee 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 devices.
-* Peers negotiate connection through [Signal Service](signal/).
-* Signal Service uses public Wireguard keys to route messages between peers.
-  Contents of the messages sent between peers through the signaling server are encrypted with Wireguard keys, making it impossible to inspect them.
-* Occasionally, the NAT-traversal is unsuccessful due to strict NATs (e.g. mobile carrier-grade NAT).
-  When this occurs the system falls back to relay server (TURN), and a secure Wireguard tunnel is established via TURN server.
-  [Coturn](https://github.com/coturn/coturn) is the one that has been successfully used for STUN and TURN in Wiretrustee setups.
+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.

+### Start using NetBird
+-  Hosted version: [https://app.netbird.io/](https://app.netbird.io/).
+-  See our documentation for [Quickstart Guide](https://netbird.io/docs/getting-started/quickstart).
+-  If you are looking to self-host NetBird, check our [Self-Hosting Guide](https://netbird.io/docs/getting-started/self-hosting).
+-  Step-by-step [Installation Guide](https://netbird.io/docs/getting-started/installation) for different platforms.
+-  Web UI [repository](https://github.com/netbirdio/dashboard).
+-  5 min [demo video](https://youtu.be/Tu9tPsUWaY0) on YouTube.
 
-### Client Configuration
-1. Login to the Management Service. You need to have a `setup key` in hand (see ).
 
-For **Unix** systems:
-```shell
-sudo wiretrustee login --setup-key <SETUP KEY>
-```
-For  **Windows** systems:
-```shell
-.\wiretrustee.exe login --setup-key <SETUP KEY>
- ```
+### A bit on NetBird internals
+-  Every machine in the network runs [NetBird Agent (or Client)](client/) that manages WireGuard.
+-  Every agent connects to [Management Service](management/) that holds network state, manages peer IPs, and distributes network updates to agents (peers).
+-  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) servers.
+-  Agents negotiate a connection through [Signal Service](signal/) passing p2p encrypted messages with candidates.
+-  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. 
+ 
+[Coturn](https://github.com/coturn/coturn) is the one that has been successfully used for STUN and TURN in NetBird setups.
 
-Alternatively, if you are hosting your own Management Service provide `--management-url` property pointing to your Management Service:
-```shell
-sudo wiretrustee login --setup-key <SETUP KEY> --management-url https://localhost:33073
-```
+<p float="left" align="middle">
+  <img src="https://netbird.io/docs/img/architecture/high-level-dia.png" width="700"/>
+</p>
 
-You could also omit `--setup-key` property. In this case the tool will prompt it the key.
+See a complete [architecture overview](https://netbird.io/docs/overview/architecture) for details.
 
-2. Start Wiretrustee:
+### Roadmap
+-  [Public Roadmap](https://github.com/netbirdio/netbird/projects/2)
 
-For **MACOS** you will just start the service:
-````shell
-sudo wiretrustee up
-# or
-sudo wiretrustee up & # to run it in background
-````   
-For **Linux** systems:
-```shell
-sudo systemctl restart wiretrustee.service
-sudo systemctl status wiretrustee.service 
-```
-For **Windows** systems:
-```shell
-.\wiretrustee.exe service start
-```
-> You may need to run Powershell as Administrator
-
-3. Check your IP:
-For **MACOS** you will just start the service:
-````shell
-sudo ipconfig getifaddr utun100
-````   
-For **Linux** systems:
-```shell
-ip addr show wt0
-```
-For **Windows** systems:
-```shell
-netsh interface ip show config name="wt0"
-```
-
-4. Repeat on other machines.  
-
-### Running Management, Signal and Coturn
-Under infrastructure_files we have a docker-compose example to run both, Wiretrustee Management and Signal services, plus an instance of [Coturn](https://github.com/coturn/coturn), it also provides a turnserver.conf file as a simple example of Coturn configuration. 
-You can edit the turnserver.conf file and change its Realm setting (defaults to wiretrustee.com) to your own domain and user setting (defaults to username1:password1) to **proper credentials**.
-
-The example is set to use the official images from Wiretrustee and Coturn, you can find our documentation to run the signal server in docker in [Running the Signal service](#running-the-signal-service), the management in [Management](./management/README.md), and the Coturn official documentation [here](https://hub.docker.com/r/coturn/coturn).
-
-> Run Coturn at your own risk, we are just providing an example, be sure to follow security best practices and to configure proper credentials as this service can be exploited and you may face large data transfer charges.
-
-Also, if you have an SSL certificate for Coturn, you can modify the docker-compose.yml file to point to its files in your host machine, then switch the domainname to your own SSL domain. If you don't already have an SSL certificate, you can follow [Certbot's](https://certbot.eff.org/docs/intro.html) official documentation
-to generate one from [Let’s Encrypt](https://letsencrypt.org/), or, we found that the example provided by [BigBlueButton](https://docs.bigbluebutton.org/2.2/setup-turn-server.html#generating-tls-certificates) covers the basics to configure Coturn with Let's Encrypt certs. 
-> The Wiretrustee Management service can generate and maintain the certificates automatically, all you need to do is run the servicein a host  with a public IP, configure a valid DNS record pointing to that IP and uncomment the 443 ports and command lines in the docker-compose.yml file.
-
-Simple docker-composer execution:
-````shell
-cd infrastructure_files
-docker-compose up -d
-````
-You can check logs by running:
-````shell
-cd infrastructure_files
-docker-compose logs signal
-docker-compose logs management
-docker-compose logs coturn
-````
-If you need to stop the services, run the following:
-````shell
-cd infrastructure_files
-docker-compose down
-````
+### Community projects
+-  [NetBird on OpenWRT](https://github.com/messense/openwrt-netbird)
 
+### 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).
