+### Setup
+
+First, build the WASM target and make inputs for Python benchmarks:
+
+```bash
+cd tpke-wasm
+wasm-pack build --release --target nodejs # Notice the target
+node scripts/make-python-bench-inputs.js
+```
+
+Then, build and install the Python package:
+
+```bash
+cd tpke-python
+pip install -e .
+```
+
+### Running
+
+```bash
+cd tpke-python
+python py-benches/benchmark.py
+
+```
+
+## Results
+
+Using fixed values, such that `shares=num_entities=threshold`.
+
+Rounding to nearest ms.
+
+### Python Results
+
+Filename refers to the number of shares.
