 # 4. Build the site (requires Node >= 20)
-cd site && npm install
-cp .env.example .env        # configure BINCIO_DATA_DIR
-bincio render               # merges edits + runs astro build

+cp site/.env.example site/.env  # configure BINCIO_DATA_DIR
+uv run bincio render            # merges edits + runs astro build
 # → open site/dist/index.html
 ```
 
 For live development with hot reload:
 ```bash
-bincio render --serve       # merges edits, links data, starts astro dev
+uv run bincio render --serve    # merges edits, links data, starts astro dev
 # → http://localhost:4321
 
 # Optional: enable the activity edit UI
-bincio edit                 # starts edit server on http://localhost:4041
+uv run bincio edit              # starts edit server on http://localhost:4041
 # Set PUBLIC_EDIT_URL=http://localhost:4041 in site/.env
