 # Sandbox development setup
 ## Website development
-You'll need Python 3 with Pip. Clone the repository and run the following:
+You'll need to
+
+* Install Flask via Python 3 with Pip in order to launch the website
+* Aquire dependencies via npm in order to make changes to the JavaScript code
+
+### Installing Flask
+[Download and install](https://www.python.org/downloads/) the latest version of Python 3 (which should come with Pip). Next, clone the repository and run the following:
 ```bash
 cd {where_you_cloned_the_repo}/Website
 pip install -r requirements.txt
 ```
-This will install Flask if you don't already have it installed. You are now ready to launch the Flask server with `./start_sandbox.sh`. All HTML/website sources are contained under the `Website` directory.
