⚙️ Initialize Gem Skeleton with Bundler​

Bundler provides a built‑in generator to scaffold a new gem complete with Rake tasks, a gemspec, and testing framework. This saves you time and ensures you're following best practices from the start. Run:

bundle gem my_cool_gem --test=rspec

This will create:

  • A my_cool_gem.gemspec file with stubbed metadata.
  • A lib/my_cool_gem.rb entry point and lib/my_cool_gem/version.rb.
  • Rake tasks for building, releasing, and running specs.

You can immediately run rake spec to verify the setup.
