-A modern, Go-based Bulletin Board System (BBS) server designed for Telnet access. It features community tools, wiki integration, and a game catalog, all rendered with retro-style ANSI graphics.
+Telnet-accessible community BBS server built on the [rubbs](https://git.teletype.hu/tools/rubbs) gem. ANSI-rendered retro terminal interface with a message board, wiki integration, and a game catalog.
 
-## Quick Start
+## Running
 
-### Prerequisites
-- [Go](https://go.dev/dl/) 1.26 or higher
-- A [Wiki.js](https://wiki.js.org/) instance (optional, for Wiki features)
+**Docker Compose (recommended):**
 
-### Installation
+```bash
+docker compose up --build
+```
 
-1. Clone the repository:
-   ```bash
-   git clone <repository-url>
-   cd bbs-server
-   ```
+**Directly (requires Ruby 3.x):**
 
-2. Install dependencies:
-   ```bash
-   go mod download
-   ```
+```bash
+bundle install
+ruby bbs.rb

-
-### Connecting
-You can connect to the BBS using any standard Telnet client:
 ```bash
 telnet localhost 2323
 ```
 
 ## Configuration
 
-- **Host/Port:** Currently hardcoded in `main.go` for simplicity.
-- **Wiki API:** Configured in `lib/repository.wiki.go`.
-- **Games API:** Configured in `lib/repository.catalog.go`.
-- **Internationalization:** Text is managed in `lib/sys.i18n.go` using a map-based system.
+Copy `env-example` to `.env` and fill in the values:
 
-## Project Structure
