 ## Configuring multiple languages
 
-Language support is provided by individual buildpacks that are shipped with the builder. The above example uses the `heroku/ruby` buildpack which is [visible on GitHub](https://github.com/heroku/buildpacks-ruby). When you execute `pack build` with a builder, every buildpack has the opportunity to "detect" if it should execute against that project. The `heroku/ruby` buildpack looks for a `Gemfile.lock` in the root of the project and if found, knows how to detect a node version and install dependencies.

 In addition to this auto-detection behavior, you can specify buildpacks through the `--buildpack` flag with the `pack` CLI or through a [project.toml](https://buildpacks.io/docs/for-app-developers/how-to/build-inputs/specify-buildpacks/) file at the root of your application.
