You can find a example Jupyter notebook inside the notebooks folder. To generate a simple script and run it, you can do

from madgrapy import madpy_generate_script, madpy_run

# Write the script
full_script_str, mg5_script_path, workdir_process = madpy_generate_script(process = "p p > t t~", models = "sm", process_name="my_first_mg5run")

# Run
mg5_script_complete_path = madpy_run(madgraph_path="/path/to/madgraph/folder", process_name = "my_first_mg5run", mg5_script_folder_path = f".")
