-**NetBird combines a configuration-free peer-to-peer private network and a centralized access control system in a single platform, making it easy to create secure private networks for your organization or home.**
+**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.**
 
-**Connect.** NetBird creates a WireGuard-based overlay network that automatically connects your machines over an encrypted tunnel, leaving behind the hassle of opening ports, complex firewall rules, VPN gateways, and so forth.
+It requires zero configuration effort leaving behind the hassle of opening ports, complex firewall rules, VPN gateways, and so forth.
 
-**Secure.** NetBird enables secure remote access by applying granular access policies, while allowing you to manage them intuitively from a single place. Works universally on any infrastructure.
+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:**
+- \[x] Automatic IP allocation and network management with a Web UI ([separate repo](https://github.com/netbirdio/dashboard))
+- \[x] Automatic WireGuard peer (machine) discovery and configuration.
+- \[x] Encrypted peer-to-peer connections without a central VPN gateway.
+- \[x] Connection relay fallback in case a peer-to-peer connection is not possible.
+- \[x] Desktop client applications for Linux, MacOS, and Windows (systray).
+- \[x] Multiuser support - sharing network between multiple users.
+- \[x] SSO and MFA support. 
+- \[x] Multicloud and hybrid-cloud support.
+- \[x] Kernel WireGuard usage when possible.
+- \[x] Access Controls - groups & rules.
+- \[x] Remote SSH access without managing SSH keys.
+- \[x] Network Routes.  
+- \[x] Private DNS.
+- \[x] Network Activity Monitoring.
+- \[x] Mobile clients (Android).
+- 
+**Coming soon:**
+-  \[ ] Mobile clients (iOS).

-### Quickstart with NetBird Cloud
-
-- Download and install NetBird at [https://app.netbird.io/install](https://app.netbird.io/install)
-- Follow the steps to sign-up with Google, Microsoft, GitHub or your email address.
-- Check NetBird [admin UI](https://app.netbird.io/).
-- Add more machines.
-
-### Quickstart with self-hosted NetBird
-
-> This is the quickest way to try self-hosted NetBird. It should take around 5 minutes to get started if you already have a public domain and a VM.
-Follow the [Advanced guide with a custom identity provider](https://docs.netbird.io/selfhosted/selfhosted-guide#advanced-guide-with-a-custom-identity-provider) for installations with different IDPs.
-
-**Infrastructure requirements:**
-- A Linux VM with at least **1CPU** and **2GB** of memory.
-- The VM should be publicly accessible on TCP ports **80** and **443** and UDP ports: **3478**, **49152-65535**.
-- **Public domain** name pointing to the VM.
-
-**Software requirements:**
-- Docker installed on the VM with the docker compose plugin ([Docker installation guide](https://docs.docker.com/engine/install/)) or docker with docker-compose in version 2 or higher.
-- [jq](https://jqlang.github.io/jq/) installed. In most distributions
-  Usually available in the official repositories and can be installed with `sudo apt install jq` or `sudo yum install jq`
-- [curl](https://curl.se/) installed.
-  Usually available in the official repositories and can be installed with `sudo apt install curl` or `sudo yum install curl`
-
-**Steps**
-- Download and run the installation script:
-```bash
-export NETBIRD_DOMAIN=netbird.example.com; curl -fsSL https://github.com/netbirdio/netbird/releases/latest/download/getting-started-with-zitadel.sh | bash
-```
-- Once finished, you can manage the resources via `docker-compose`

 ### 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).
