+## Quickstart (Dashboard)
+
+Install minimal dashboard deps:
+
+`python3 -m pip install -r requirements-dashboard.txt`
+
+Run:
+
+`SECOND_BRAIN_WORKSPACE="$(pwd)" python3 fastapi_app.py`
+
+Then open: `http://localhost:8501/`
+
+Port is configurable via `SECOND_BRAIN_PORT` (or `PORT`), e.g.:
+
+`SECOND_BRAIN_WORKSPACE="$(pwd)" SECOND_BRAIN_PORT=8502 python3 fastapi_app.py`
