# Introduction **Welcome to Jack’s Notebook.** \ This space collects the ideas, notes, and resources behind my videos, projects, and ongoing work. Think of it as a personal knowledge base—a living menu of what I’m building, testing, and learning. Here you’ll find project documentation, software recommendations, 3D printing workflows, and technical experiments. For my finished design work and design-focused projects, please visit the separate design page. This notebook is simply where everything starts. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://notebook.jinjiejackwang.com/master.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
