+# DorkNet
+
+A self-hostable reimplementation of the 2020 Rec Room backend. Bring your own
+client; run a private server for yourself and your friends.
+
+> ⚠️ **Not affiliated with Rec Room Inc. or Against Gravity.**
+> See [DISCLAIMER.md](DISCLAIMER.md). DorkNet ships no Rec Room game assets or
+> modified binaries — you supply your own legally-acquired Rec Room 2020.03.10
+> install.
+
+---
+
+## Two ways to run it
+
+### 🎮 Easy mode — desktop app
+
+One download. Double-click. Choose "host" or "join" on first launch.
+
+- **Host a server** for you and your friends — runs a local server + tunnel,
+  patches your Rec Room install, and gives you a shareable join code.
+- **Join a server** someone shared with you — paste the code, point at your
+  Rec Room install, hit play.
+
+→ **[Easy setup guide](docs/easy-setup.md)** — screenshots, takes 5 minutes.
+
+[Download the latest Easy app →](https://github.com/YOUR_GH_USERNAME/dorknet/releases/latest)
+
+### 🛠️ Advanced mode — Docker
+
+For people running a community server, doing custom modding, or contributing
+back. Postgres + Redis + the ASP.NET Core server behind an nginx reverse proxy.
+
+```bash
+git clone https://github.com/YOUR_GH_USERNAME/dorknet
+cd dorknet/docker
+cp .env.example .env  # fill in 2-3 values
+docker compose up -d
+```
