# Usage Example This example showcases how to bind library dependencies and execute the `Aesop` tactic in Lean. First build the example project: ``` sh pushd Example lake build popd ``` This would generate compiled `.olean` files. Then run one of the examples from the project root: ``` sh poetry run examples/aesop.py poetry run examples/data.py ``` Warning: If you make modifications to any Lean files, you must re-run `lake build`!
