We provide an example to test the Nova verifier. The build folder already contains the artifacts generated by the circuit compilation. If you want to recompile the circuit, you can run the following command:
```
-circom src/circom/incremental_mst_inclusion.circom --r1cs --wasm -o examples/build --prime bn128
+$ cd src/circom
+$ npm install
+$ circom incremental_mst_inclusion.circom --r1cs --wasm -o ../../examples/build --prime bn128

To run the Nova Incremental Verifier example run:
