-NixOS module for IPv6 networking with WireGuard tunnels and optional BGP failover.
+IPv6 WireGuard tunnels with optional BGP failover.
 
 ## Motivation
 
 My ISP gives me a single `/64` and it's dynamically assigned. Can't have multiple networks with functional autoconfiguration. Tunnel brokers like [Hurricane Electric](https://tunnelbroker.net/) would work but my ISP uses CGNAT which makes that setup tricky if not impossible. They also do not have any exit nodes in the region I want.
 
-Linode provides a routed `/56` for free with their cheapest $5/month VPS. That's 256 `/64` subnets. You get 1TB traffic at 1Gbit (40Gbit input but that's kind of irrelevant for our use case). Good enough.

 Just a plain WireGuard tunnel to route the `/56` to your home network.

 - Interfaces get `/64`s from the delegated `/60` with router advertisement enabled
 - All traffic from clients goes out to the internet via Linode
 
-## Solution 2: BGP failover (ultra advanced)
+## Solution 2: WireGuard tunnels with BGP for failover
 
 Want redundancy? Run two Linodes in the same datacenter and use BGP to share a single `/56` between them. If one server goes down, BGP automatically fails over to the other.
