Hello, nontechnical tinkerer here. Trying to build off of the Starter Tutorial (
https://gpt-index.readthedocs.io/en/latest/getting_started/starter_example.html), where it asks you to create a folder called data, and add a Paul Graham essay as a .txt document in it. As a total newbie, it was cool to get everything working through the CL when I tried the tutorial. But now I want to add new documents to the Index that started with that Paul Graham essay; how can I do this? What is the Python script I could run that would take new .txt documents in the data folder with the Paul Graham essay already in it, and add it to the Index. So I can add my own documents instead of only being able to ask about PG. I think a lot of punters will start like me, so it'd be nice to have a manageable way to add new content to that index so I can ask question about my own documents/data and not just about Paul Graham.
