+# Python Evaluation Interop
+
+This package is currently a proof-of-concept for running the 
+evaluation-interop module as a shared library in python utilizing the CFFI package.
+
+## Install dependencies
+
+(Assuming python 3.9 installed)
+
+1. Install CFFI via pip
+   ```
+   pip install cffi
+   ```
+
+## Setup & Run Proof-of-concept
+
+(Assuming macosX64)
+
+1. Build the `evaluation-interop` shared library. From the root `experimentation-evaluation` directory:
+   ```
+   ./gradlew evaluation-interop:build
+   ```
+2. Copy the shared library into `/usr/local/lib`:
+   ```
+   sudo cp evaluation-interop/build/bin/macosX64/debugShared/libevaluation_interop.dylib /usr/local/lib
+   ```
+3. Copy the header file to the `python` directory:
+   ```
+   cp evaluation-interop/build/bin/macosX64/debugShared/libevaluation_interop_api.h python 
+   ```
+4. Change to `python` directory and run `setup.py`:
+   ```
+   cd python
+   python setup.py
+   ```
+5. Run the proof-of-concept python file to run an evaluation:
+   ```
+   python main.py
+   ```
