 # p2p-forwarder
-Tool for farwarding ports. Made using libp2p.
+
+[![Go Report Card](https://goreportcard.com/badge/github.com/nickname32/discordhook)](https://goreportcard.com/report/github.com/nickname32/p2p-forwarder)
+
+Tool for farwarding ports. Made using [libp2p](https://github.com/libp2p/go-libp2p).
+
+![screenshot](https://i.imgur.com/BMFXKNK.png)
+
+## How it works
+
+- A: opens desired ports ports inside P2P Forwarder
+- A: shares it's id from P2P Forwarder with B
+- B: connects to A's id inside P2P Forwarder
+- B: connect to opened ports on A's machine using address like 127.0.89.N:PORT_ON_A's_MACHINE
+
+P.S. every edit field handles Ctrl+C and Ctrl+V. To exit the program, press Ctrl+Q
+
+## Project status
+
+Project is on early beta stage. I recommend you to use it only for personal purposes like playing Minecraft with friends.
+
+Current ui is using [clui](https://github.com/VladimirMarkelov/clui), but i'm working on more comfortable one, which will be using [gotk3](https://github.com/gotk3/gotk3) (bindings to gtk3)
+
+Also i'm thinking about making cli.
