The Superhero Sandbox is the place for you to launch and execute py-trello python module that will effect the changes on your board. It is a place for you to learn and explore the modules before putting them into productive use.
You do this by identifying a module from a library of pre-built and tested modules. Each module comes with a brief description, the input requirements including to run the module including the module ID, a link to inspect the actual code in GitHub and the expected output.
Once the required input has been customised you are ready to launch and execute the module.
