+# Gastown (Go)
+
+Go port of [Gas Town](https://github.com/steveyegge/gastown-py) - a multi-agent workspace manager.
+
+## Status
+
+**Work in Progress** - This is the Go rewrite of the Python gastown tool.
+
+See the [Python version](https://github.com/steveyegge/gastown-py) for current functionality.
+
+## Goals
+
+- Single binary installation (`gt`)
+- Self-diagnosing (`gt doctor`)
+- Federation support (coordinate agents across VMs)
+- Performance improvements over Python version
+
+## Development
+
+```bash
+# Build
+go build -o gt ./cmd/gt
+
+# Run
+./gt --help
+```
