If your project requires a specific Ruby version, you can configure it by following these steps:

1. Update asdf plugins:

   asdf plugin update --all
   

2. List available Ruby versions:

   asdf list all ruby
   

3. Install the desired version:

   asdf install ruby <VERSION>
   

4. Set the active version:

   • Globally (sets the version for all directories):

     asdf global ruby <VERSION>
     

   • Locally (sets the version for the current directory only):

     asdf local ruby <VERSION>
     

     This command creates a .tool-versions file in your project directory to specify the Ruby version.

5. Verify the active Ruby version:

   ruby -v
