+# R in Gitpod
+
+In order to work with R in Gitpod, you will need to properly configure your repository. Here is how to do it.
+
+## Installing R
+
+First you'll probably want to install R itself. To do this, add a new file to your repository called [`.gitpod.Dockerfile`](https://www.gitpod.io/docs/config-docker/), and add the following content to it:
+
+```Dockerfile
+FROM gitpod/workspace-full
+
+RUN brew install R
+```
+
+Next, create a Gitpod configuration file called `.gitpod.yml` (you can also simply run `gp init` and Gitpod will generate the file), and reference the above Dockerfile in it like so:
+
+```yml
+image:
+  file: .gitpod.Dockerfile
+```
+
+Then commit and push both files to your repository. After that, every new Gitpod workspace created for your project will have R pre-installed.

+To install the R extension to your repository, add the following to your [`.gitpod.yml`](https://www.gitpod.io/docs/config-gitpod-file/) file:
+
+```yaml
+vscode:
+  extensions:

+```

+Here is a minimal example of [R running in Gitpod](https://github.com/gitpod-io/Gitpod-R). You can try it here:
