 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.
 
 **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.
