-# Multiplier example
-
-Example wrapper around a basic Circom circuit to test Circom 2 integration
-through ark-circom and FFI.
-
-## Build and Test
-
-To build and test, run the following commands within the module folder
-```bash
-cargo make build
-cargo make test
-```
-
-## FFI
-
-To generate C or Nim bindings from Rust FFI, use `cbindgen` or `nbindgen`:
-
-```
-cbindgen . -o target/multiplier.h
-nbindgen . -o target/multiplier.nim
-```
