 ## What is in `{ghactions4r}`?
 
-This repo contains a [collection of reusable workflows](https://github.com/nmfs-fish-tools/ghactions4r/tree/main/.github/workflows) found helpful for R packages. In addition, {ghactions4r} contains helper functions for setting up the workflows in a separate R package GitHub repository. Rather than having to maintain your own GitHub actions files (as you would need to with actions set up with [`usethis::use_github_action()`](https://usethis.r-lib.org/reference/use_github_action.html)), using a `{ghactions4r}` `use_*` function sets up a github actions file to directly call actions that exist and are maintained in the `{ghactions4r}` repository (in the [workflows folder](https://github.com/nmfs-fish-tools/ghactions4r/tree/main/.github/workflows)). This means all maintenance happens within the `{ghactions4r}` repository rather than in your repository!
