 Use `make` command to build the images. Before starting the arm32v7 platform build, you need to run this registry, so you can perform a cross-build. Just follow the documentation: https://github.com/multiarch/qemu-user-static/blob/master/README.md
 
 ```sh
-$ TARGET_ARCHITECTURE=[arm32v7, x86_64, (nothing to build all architectures)] make
+$ N2N_COMMIT_HASH=[(optional)] TARGET_ARCHITECTURE=[arm32v7, x86_64, (nothing to build all architectures)] make platforms
