+# VortexDB TUI
+
+A terminal user interface for managing VortexDB databases locally.
+
+## Important Note
+
+> **This is currently a local admin/development tool**, not a network client. The TUI operates directly on database files using embedded storage — it does not connect to a running VortexDB server. This will change once the server gets the multiple-database support.
+>
+> For remote server access, use the [Python client](../../client/python/).
+
+## Usage
+
+```bash
+cargo run -p tui
+```
+
+Databases are stored in `./databases/` by default.
+
+### Environment Variables
+
+For embedding features, set these in your `.env` file or environment:
+
+```bash
+TEXT_EMBEDDING_URL=http://localhost:8000/embed/text
+IMAGE_EMBEDDING_URL=http://localhost:8000/embed/image
+```
+
+These point to an external embedding service that generates vectors from text/images.
+
+## Roadmap
+
+This TUI will evolve into a full client that connects to VortexDB servers over gRPC. Planned changes:
+
+- Add remote connection mode via gRPC (like the Python client)
+- Move to `client/tui/` once server multi-database support lands
