+# Setting up TK-Wave for development
+
+Welcome! This page outlines a guide to get started with developing for Turbine Kernel (TK) Wave.
+
+## Setting up
+
+For setting up necessary environments and tools, first follow the instructions under "Developers" in the main [README](../README.md). Specifically, while in the root `iree-turbine` directory, do the following:
+
+### Create a virtual environment
+
+This will consolidate all necessary python packages for your project in one folder. GitHub will ignore the virtual environment if you name it `.venv` (see `.gitignore`).
+
+```
+python -m venv --prompt iree-turbine .venv #Create the virtual environment
+source .venv/bin/activate #Activate the virtual environment. Must run any time you start a new terminal.
+```
+
+### Installing PyTorch
+
+PyTorch is our friendly frontend for AI work, and we'll be using it to compare our computational results with their "golden standard".
+
+*For CPU:*
+
+```
+pip install -r pytorch-cpu-requirements.txt
+```
+
+*For ROCM:*
+
+```
+pip install -r pytorch-rocm-requirements.txt
+```
+
+### Install Development Packages
+
+Finally, install all other required Python packages.
+
+```
+pip install -r requirements.txt -e .
+```
+
+# Testing
+
+Try running `tests/kernel/wave/wave_e2e_test.py`. Even with venv activated and shark_turbine installed, you might still get ModuleNotFoundError: No module named 'shark_turbine'. Me too! But why?
+
+You even try running:
+
+* `kernel/wave/wave_e2e_test.py` from `iree-turbine/sharktank`
+* `wave/wave_e2e_test.py` from `iree-turbine/sharktank/kernel`
+* `wave_e2e_test.py` from `iree-turbine/sharktank/kernel/wave`
+
+... I need some help
