| The models created during resampling are independent of one another. Computations of this kind are sometimes called *embarrassingly parallel*; each model could be fit simultaneously without issues.^[@parallel gives a technical overview of these technologies.] The `r pkg(tune)` package uses the [`r pkg(foreach)`](https://CRAN.R-project.org/package=foreach) package to facilitate parallel computations. These computations could be split across processors on the same computer or across different computers, depending on the chosen technology. | ||

Another PR is coming with more content changes for the new versions.
