+# ETH 2.0 py-tests
+
+These tests are not intended for client-consumption.
+These tests are sanity tests, to verify if the spec itself is consistent.
+
+There are ideas to port these tests to the YAML test suite,
+ but we are still looking for inputs on how this should work.
+
+## How to run tests
+
+From within the py_tests folder:
+
+Install dependencies:
+```bash
+python3 -m venv venv
+. py_tests/venv/bin/activate
+pip3 install -r requirements.txt
+```
+
+Run the tests:
+```
+pytest -m minimal_config .
+```
