+# Terraria Dedicated Server (Docker)
+
+Lightweight Terraria dedicated server image built from the official server zip.
+
+## Build
+
+```bash
+docker build -t terraria-server .
+```
+
+To build a specific Terraria version:
+
+```bash
+docker build --build-arg T_VERSION=1451 -t terraria-server:1451 .
+```
+
+## Run
+
+```bash
+docker run --rm -it \
+  -p 7777:7777/tcp -p 7777:7777/udp \
+  -v "$PWD/config:/config" \
+  -v "$PWD/worlds:/worlds" \
+  terraria-server
+```
+
+## Configuration
+
+- Config file default: `/config/serverconfig.txt`
+- World path default: `/worlds`
+
+You can override these with environment variables:
+
+```bash
+docker run --rm -it \
+  -e CONFIG_FILE=/config/serverconfig.txt \
+  -e WORLD_PATH=/worlds \
+  -p 7777:7777/tcp -p 7777:7777/udp \
