 # webr-org-gh-action
-Example repository that strictly follows the guidance for setting up a mini-CRAN repo for webR R WASM Package binaries.
+
+This repository serves as an example that strictly follows the [guidance](https://r-wasm.github.io/rwasm/articles/github-actions.html) for setting up a mini-CRAN repo for webR R WASM Package binaries.
+
+If you would like to have the repository where you develop your R package build and act as a deployment repository, then see the [coatless-tutorials/webr-github-action-wasm-binaries](https://github.com/coatless-tutorials/webr-github-action-wasm-binaries) repository. 
+
+## Setup `packages`
+
+When trying to setup an environment for your own packages, please make sure to modify the `packages` file to contain the appropriate [package reference value supported by `pak`](https://r-lib.github.io/pkgdepends/reference/pkg_refs.html). In the case of generating [R WASM package binaries from GitHub](https://r-lib.github.io/pkgdepends/reference/pkg_refs.html#github-packages-github-), you can achieve this with: 
+
+```
+gh-username/reponame
+```
+
+Or, more formally with: 
+
+```
+github::gh-username/reponame
+```
+
+Need a [package from CRAN](https://r-lib.github.io/pkgdepends/reference/pkg_refs.html#cran-packages-cran-)? This can be specified as: 
+
+```
+pkgname
+```
