    # Installing Ruby 3.3.5 with YJIT on Macbook with ASDF

    ## Install ASDF
    Ensure you have homebrew installed. See https://brew.sh

    ```shell
    brew install coreutils curl git libyaml asdf
    ```

    ### Add the ZSH plugin

    Add the following to ~/.zshrc

    ```shell
    plugins=(asdf)
    ```

    ## Install Rust
    If you want YJIT in Ruby, you'll need to install Rust.

    ```shell
    asdf plugin add rust
    asdf install rust latest
    asdf global rust latest
    ```

    ### Install Ruby

    ```shell
    asdf plugin add ruby
    export RUBY_CONFIGURE_OPTS=--enable-yjit
    asdf install ruby 3.3.5

    # Optionally
    asdf global ruby 3.3.5
    ```

    # Verify installation with:
    ```shell
    ruby -v --yjit
    ```
