 | Variant | Description                                                  |

-## Move code interactions
-
-From within any variant directory, for example `variants/a`:
-
-1. Ensure `movefmt` is installed:
-
-   ```sh
-   aptos update movefmt
-   ```
-
-1. Test and format:
-
-   ```sh
-   aptos move test --dev --move-2
-   aptos move fmt
