-### Installing dependencies
-
-Install the required dependencies from the `requirements.txt` file.
-
-If using `pip` then `pip install requirements.txt`.
-
-If using `conda` then follow these steps to create an environment with the right dependencies:
-
-```bash
-conda create --name Python-VPP \
-    && conda config --add channels conda-forge \
-    && conda activate Python-VPP \
-    && conda install -y --file requirements.txt
-```
-
-### Running tests
+Please see the demo hosted at [https://yacht-vpp.streamlit.app/](https://yacht-vpp.streamlit.app/) and go for a test sail!
 
-Tests are implemented using [pytest](https://docs.pytest.org/en/8.0.x/).
-
-You can run tests with
-
-```bash
-pytest -vv
-```
-
-You can run a benchmark against the YD-41 results from WinVPP by running the `benchmark.py` script.
-
-```bash
-$ python benchmark/benchmark.py -g -o
