+## Python development setup
+
+The e2e tests are being migrated to pytest. This section covers setting up the Python environment.
+
+### Installing uv
+
+[uv](https://github.com/astral-sh/uv) is used for Python dependency management. Install it via make:
+
+```
+make uv
+```
+
+Or manually:
+
+```
+curl -LsSf https://astral.sh/uv/install.sh | sh
+```
+
+### Python make targets
+
+```
+make py-deps          # Install Python dependencies (locked versions)
+make py-update-deps   # Update Python dependencies
+make py-fmt           # Format code and organize imports with ruff
+make py-check         # Run ruff linter and mypy type checks
+```
+
+### Running tests with pytest
+
+First, install dependencies:
+
+```
+make py-deps
+```
+
+Run all pytest-based tests:
+
+```
+uv run pytest e2e-tests/
+```
+
+Run a specific test file:
+
+```
+uv run pytest e2e-tests/init-deploy/test_init_deploy.py
+```
+
+Run a specific test:
+
+```
+uv run pytest e2e-tests/init-deploy/test_init_deploy.py::TestInitDeploy::test_cluster_creation
+```
+
+Run tests matching a pattern:
+
+```
+uv run pytest e2e-tests/ -k "init"
+```
