+# Overview
+
+Communicating across platforms in a decentralized manner
+
+## Decisions
+
+- Limit dependency on WebSockets to signaling
+- Allow bidirectional communication between peers
+- Enforce locality of device?
+
+## Implementation
+
+A WebSocket Service should establish the SDP handshake and emit ICE candidates for WebRTC clients.
+
+This implementation should replace Wallet Connect with the following sequence
+```mermaid

+```
+
+*Note: This process may be deprecated in the future in favor of `libp2p` which allows for an agnostic discovery layer and also supports the WebRTC transport

-## Getting started
-
-### Prerequisites
-- Node.js 20
-- Docker
-
-#### Clone the project
-
-```bash
-git clone [email protected]:algorandfoundation/liquid-auth.git && cd liquid-auth
-```
-
-#### Install package dependencies
-
-```bash
-npm install
-```
-
-#### Start services
-
-```bash
-docker-compose up -d
-```
-
-WebAuthn requires a secure context (HTTPS) to work and this will not allow you to test the FIDO2 feature in your local machine.
-
-### NGROK
-
-Sign up for a free account at [ngrok](https://ngrok.com/) and install the ngrok package.
-Configure a Static Domain for your ngrok account and update the [.env](services/liquid-auth-api-js/README.md) file with the following keys with the values from ngrok:
-
-```bash
-HOSTNAME=example-static-domain.ngrok-free.app
-ORIGIN=https://example-static-domain.ngrok-free.app
-```
-
-#### Run the ngrok proxy
-
-```bash
-ngrok http --domain=example-static-domain.ngrok-free.app 3000
-```
-
-#### Run the Authentication Service 
-```bash
-npm run dev
-```
-
-Navigate to the ngrok URL in your browser to test the FIDO2 feature.
