## Requirements

* A working setup of [Lean 4](https://lean-lang.org/), including [elan](https://github.com/leanprover/elan) and [Lean's VSCode extension](https://lean-lang.org/lean4/doc/quickstart.html)
* Install the latest version of [Z3](https://github.com/Z3Prover/z3) and [CVC5](https://cvc5.github.io/) and make sure they can be accessed from the command line
* Install Python dependencies: `pip install smt-portfolio openai`
* Find out the location of `smt-portfolio` and make sure Lean's VSCode extension can also access it. For example, if `which smt-portfolio` outputs `/Users/yangky/miniconda3/envs/lean/bin/smt-portfolio`, you should set `Server Env Paths` in Lean's VSCode extension as below:
