-**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.**
+**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.**
 
-It requires zero configuration effort leaving behind the hassle of opening ports, complex firewall rules, VPN gateways, and so forth.
+**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.
 
-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.

-**Coming soon:**
-- \[ ] Mobile clients.
+**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.

+### 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).

 ### Support acknowledgement
 
 In November 2022, NetBird joined the [StartUpSecure program](https://www.forschung-it-sicherheit-kommunikationssysteme.de/foerderung/bekanntmachungen/startup-secure) sponsored by The Federal Ministry of Education and Research of The Federal Republic of Germany. Together with [CISPA Helmholtz Center for Information Security](https://cispa.de/en) NetBird brings the security best practices and simplicity to private networking.
