## Overview

This repository packages a single persistent SimpleX SMP relay for Railway. A user obtains connection details from the public HTTP status page, configures SimpleX Chat with an SMP address, and connects through Railway’s TCP proxy and the TCP adapter to the relay. The relay’s identity and queues persist on a Railway volume. The README documents these components and relationships, but no source excerpts were provided, so implementation ownership beyond the named entrypoint and container configuration is not verified.

Main entry points: [`entrypoint.sh`](https://github.com/darkstaraurorashockwave/railway-template-simplex-chat/blob/main/entrypoint.sh) (TCP adapter), [`Dockerfile`](https://github.com/darkstaraurorashockwave/railway-template-simplex-chat/blob/main/Dockerfile) (SMP relay)

## Connections

- Relay operator → HTTP status page: reads connection details (evidence: `README.md`)
- Relay operator → SimpleX Chat: configures server (evidence: `README.md`)
- SimpleX Chat → Railway TCP proxy: connects via TCP (evidence: `README.md`)
- Railway TCP proxy → TCP adapter: forwards TCP (evidence: `README.md`)
- TCP adapter → SMP relay: forwards to relay (evidence: `README.md`)
- SMP relay → Persistent volume: persists identity and queues (evidence: `README.md`)
