 ### Setting up dev environment (project development bootstrap)
 
 - Uses `multiversx-sc-* 0.39.4` SDK libs (see Cargo.toml)
-- Building requires minimum **mxpy 5.2.3** (newer version should also work but devs used 5.2.3). Check version using `mxpy --version`
+- Building requires minimum **mxpy 6.1.1** (newer version should also work but devs used 6.1.1). Check version using `mxpy --version`
 - To build the project, requires minimum Rust version `1.68.0-nightly`. Check your Rust version by running `rustc --version`. To update your Rust, run `rustup update`. To set to nightly run `rustup default nightly` (devs used 1.69.0-nightly)
 - After you make sure you have the minimum Rust version you can then begin development. After you clone repo and before you run build, deploy or run the tests - follow these steps (most likely only needed the 1st time)
