A "Hello, world" experiment

Creating a hello-world experiment is as easy as writing this script.py file. You can even do it in a simple text editor. Note that the file must be named script.py

import alfred3 as al
exp = al.Experiment()
exp += al.Page("Hello, world!", name="hello_world") 

To run the script, open a terminal and change the working directory to your experiment directory:

$ cd path/to/experiment

Next, simply execute the following command in the terminal::

$ alfred3 run

If you have Google Chrome installed on your machine, a browser window with the experiment opens automatically. Otherwise, open any webbrowser and visit http://127.0.0.1:5000/start to start the experiment.

Of course, this "Hello, world" experiment does not contain much content: Only a single page with a heading. To learn how to add content to an experiment, visit our tutorials: (to be filled)
