 If you'd like to develop in this manner, you may do so by running the following and changing `<password>` to a password of you choosing at the command line:
 
 ```bash

 You can change the volume that the Docker container points to either via the [Kitematic GUI](https://docs.docker.com/kitematic/userguide/) or the [`--volume` flag](https://docs.docker.com/storage/volumes/) to `docker run`.
 For example, from your cloned `OpenPedCan-analysis` folder, run the command below:
 
 ```bash
-docker run --name <CONTAINER_NAME> -d -e PASSWORD=pass -p 8787:8787 -v $PWD:/home/rstudio/OpenPedCan-analysis pgc-images.sbgenomics.com/d3b-bixu/open-pedcan:latest

 ```
 
 Once you've set the volume, you can navigate to `localhost:8787` in your browser if you are a Linux or Mac OS X user.
