-Tinc is a newer VPN technology that allows you to create partial/full mesh VPN connections without having to define every endpoint, as you'd have to with other VPN protocols. A minimum amount of configuration is still needed for each site. However, it's the quickest way to develop a mesh VPN between network sites.
+Tinc is a newer VPN technology. Unlike with other protocols, it lets you create partial/full mesh VPN connections without having to define every endpoint. A minimum of configuration is needed for each site. It's the quickest way to develop a mesh VPN between network sites.
 The Tinc Daemon menu is divided into tabbed sections, including Tinc Configuration, and (VPN) Hosts.

-**Interface type:** TUN/TAP: Here, you specify the communication protocol used within your VPN. TUN is routed, and runs at the network (IP) layer. TAP is switched, and runs at the datalink layer.

-**Compression:**  In some cases, compression may increase VPN speeds. The default of "0" (disabled) can be adjusted as high as "11". All nodes must be configured with the same setting.
