+I share it because, some people might find it useful and other might find ways to improve it.
+
+## Setup
+
+### Just
+
+You'll need the task runner [just](https://github.com/casey/just) - see the [install section](https://github.com/casey/just?tab=readme-ov-file#packages).
+
+If you are on MacOS, you can install it with Homebrew:
+
+```sh
+brew install just
+```
+
+### Compilation targets
+
+Whether you compiling from intel or arm, you will need to add the missing target - see the installed targets: `rustup target list|grep installed`.
+
+```sh
+rustup target install x86_64-apple-darwin # if you're on arm and missing the intel target
+rustup target install aarch64-apple-darwin # if you're on intel and missing the arm target
+```
