 This crate allows the creation and usage of Tun/Tap interfaces(**supporting both Ipv4 and ipv6**), aiming to make this cross-platform.
 
+## Features:
+1. Supporting TUN and TAP(macOS only support TUN)
+2. Supporting both IPv4 and IPv6
+3. Supporting Synchronous and Asynchronous API
+4. Supporting Tokio and async-std asynchronous runtimes
+5. All platforms have consistent IP packets(macOS's 4-byte head information can be eliminated).
+6. Experimentally supporting shutdown for Synchronous version
+7. Supporting Offload on the Linux platform.
