+#  Template for RStudio on Binder / JupyterHub
+
+[![Binder](https://mybinder.org/badge_logo.svg)](https://mybinder.org/v2/gh/yuvipanda/rstudio-binder-template/HEAD?urlpath=rstudio)
+
+Generate a Git repository that can run R code with RStudio on
+the browser via [mybinder.org](https://mybinder.org) or any JupyterHub
+from this template repository!
+
+Based on the excellent [rocker/binder](https://hub.docker.com/r/rocker/binder)
+image maintained by the [Rocker project](https://www.rocker-project.org/)
+
+## How to use this reop
+
+### 1. Create a new repo using this as a template
+
+Use the [Use this template](https://docs.github.com/en/repositories/creating-and-managing-repositories/creating-a-repository-from-a-template#creating-a-repository-from-a-template)
+button on GitHub. Use a descriptive name representing the
+GUI app you are running / demoing. You can then follow the rest of
+the instructions in this README from your newly created repository.
+
+### 2. Install any packages you want
+
+You can create an `install.R` file that will be executed on build.
+Use `install.packages` or `devtools::install_version`.
+
+```R
+install.packages("ggplot2")
+```
+
+Packages are installed from [packagemanager.rstudio.com](https://packagemanager.rstudio.com/client/#/),
+and binary packages are preferred wherever possible. For some R packages,
+you might need to install system packages via apt - you can do so by writing
+out a list of apt package names in `apt.txt`.
+
+### 3. Modify the Binder Badge in the README.md
+
+The 'Launch on Binder' badge in this README points to the template repository.
+You should modify it to point to your own repository. Keep the `urlpath=rstudio`
+parameter intact - that is what makes sure your repo will launch directly into
+RStudio
+
+### 4. Add your R code and update README
+
+Finally, add the R code you want to demo to the repository! Cleanup the README
+too so it talks about your code, not these instructions on setting up this repo
