+# shChat Bridge
+
+A Peer to Peer bridge between Discord and sshChat using [Hyper-Protocol](https://docs.holepunch.to/)
+
+
+A high-level API for finding and connecting to peers who are interested in a "topic." 
+
+[@hyperswarm/dht](https://docs.holepunch.to/building-blocks/hyperswarm#dht): 
+
+A DHT powering Hyperswarm. Through this DHT, each server is bound to a unique key pair, with the client connecting to the server using the server's public key.
+
+
+[@hyperswarm/secretstream](https://docs.holepunch.to/building-blocks/hyperswarm#secretstream): 
+
+Secretstream is used to securely create connections between two peers in Hyperswarm.
+
+## What is HyperSwarm?
+Hyperswarm allows you to find and connect to peers who are announcing a common "topic". The swarm topic can be anything. This means that, with Hyperswarm, you can discover and connect peers with a shared interest over a distributed network. As an example, we often use Hypercore's discovery key as the swarm topic for discovering peers to replicate with.
+Once Hyperswarm has discovered peers, nodes in the DHT help those peers connect via a UDP-based hole-punching algorithm that's designed to work well in home networks.
+
+https://docs.holepunch.to/building-blocks/hyperswarm
+
+## Usage
+
+To install:
+
+`git clone git@git.codingvm.codes:snxraven/sshChatBridge.git`
+
+`cd sshChatBridge`
+
+`npm i`
+
+To run a new topic (room):
+
+`node bot.js`
+
+This will log the bot into Discord.
+
+
+To set a topic use the !set-topic command within the channel you wish to bridge.
+
+The bot will provide a connection topic hash to connect to.
+
+Once a peer connects all messages will be sent both ways.
+
+!leave [TOPIC HASH] will destroy a topic bridge.
