Installation and Setup Instructions:

• Install Python Flask. Flask can be found at: http://flask.pocoo.org/. Make sure to install Pyton Flask's dependencies: the Jinja2 template engine and the Werkzeug WSGI toolkit.
• Clone this repository.
• Navigate to the static folder and clone the following repository: https://github.com/jonatho7/Snap--Build-Your-Own-Blocks. This repository is not setup as a submodule. I chose to keep these two repositories separate for the sake of simplicity. However, remember to commit your changes to both repositories if you make changes in both repositories.
• The repository mentioned above is named "Snap" on my machine. It is important that this repository be named "Snap" and not "Snap--Build-Your-Own-Blocks". Change the name of this folder if necessary.

Run Snap:

• Open up a command prompt in the SnapBYOBServer repository folder.
• Run: routes.py If the installation went as planned you should see a message on the next two lines of the command prompt:
  • Running on http://127.0.0.1:5000/
  • Restarting with reloader
• Open up a web browser.
• Navigate to http://127.0.0.1:5000/snap and Snap will load. That it. Enjoy!
