 As of now, *WASM* builds have a minimum requirement of `Clang` version 16 or later (version 18 is the latest at the time of writing this doc). If you're using *Ubuntu 22.04 LTS* or older, then you will have to add an additional repository to `apt` to be able to get said version. Run the following commands on your terminal to do this:
 
 ```bash
-sudo add-apt-repository -y "deb http://apt.llvm.org/$(lsb_release -s -c)/ llvm-toolchain-$(lsb_release -s -c)-18 main"

 If you're planning to use your environment to do Linux cross-building to other architectures (e.g. Arm32, Arm64), and/or other operating systems (e.g. Alpine, FreeBSD), you'll need to install a few additional dependencies. It is worth mentioning these other packages are required to build the `crossrootfs`, which is used to effectively do the cross-compilation, not to build the runtime itself.
