Okay, I need to create a Wikipedia-style document about the GNU Project under the categories of Technology, Software, and Open Source. Let me start by understanding the requirements.

First, the structure: H1 for the title, an overview section, several sections with H2 and H3, and maybe references or related documents. The content needs to be accurate, objective, detailed enough, easy to read, and use technical terms with explanations. Also, markdown formatting with proper headings, lists, tables, code blocks if needed, and at least 800 characters.

Starting with the title: "GNU 프로젝트" as given. Then an overview section introducing what GNU is, its purpose, and maybe some key points like the Free Software Foundation (FSF) and the GPL license.

Next sections. Maybe break it down into History, Core Principles, Key Components, Impact on Open Source, Challenges, and Related Documents. Each of these can be H2 sections. Under each, add H3 for sub-sections if needed.

For the history section, I should mention Richard Stallman's founding in 1983, the goals of creating a free operating system, and milestones like the GNU General Public License (GPL) version 1 in 1989. Maybe include when the first were released and how it evolved over time.

Core Principles: Talk about the four freedoms of free software, the philosophy behind them, and how they differ from open source. Also mention the FSF's role here.

Key Components: List major GNU tools like GCC, GDB, Bash, etc. Maybe a table with each tool, its purpose, and version Or just describe them in bullet points with brief explanations.

Impact on Open Source: Discuss how GNU contributed to the development of Linux and the broader open-source movement. Mention the combination of Linux kernel with GNU tools as the basis for many distributions. Also touch on the GPL's influence on other licenses.

Challenges: Possible issues like the initial lack of a complete system, legal challenges, or debates around the term "free software" versus "open source." Maybe mention the FSF's stance on proprietary software and how that affects adoption.

References: Include links to official websites, key documents like the GPL, and related projects. Also, maybe some books articles about the history of GNU.

Need to ensure technical terms are explained. For example, when mentioning GPL, explain what it is in simple terms. Avoid jargon without explanation.

Check for accuracy: Make sure dates, names, and project details are correct. For instance, Stallman founded GNU in 1983, the first version of GCC was released in 1987, etc.

Also, ensure that each section flows logically. The overview should set the stage, then dive into history, principles, components, impact, challenges, and related info.

Use markdown formatting: H1 for title, H2 for main sections, H3 for subsections if needed. Use bullet points or numbered lists where appropriate. Maybe a table for key components.

Check length: 800 characters is about 150-200 words. The entire document should be longer than that. Need to elaborate each section sufficiently.

Potential issues: Making sure the content isn't too brief For example, in the Key Components section, just listing tools might not be enough. Need to explain their significance and how they contribute to the GNU projectAlso, avoid any subjective language. Keep it factual. For instance, instead of saying "GNU is the best," state its role and contributions objectively.

Double-check for any errors in information. For example, confirming that the GPL was first released in 1989, not a different year. Also, verifying the names of tools like GDB (GNU Debugger), GCC (GNU Compiler Collection), etc.

Including code blocks if there's any relevant code examples, but since it's about the project itself, maybe not necessary unless discussing license text. But perhaps include a snippet of the GPL license terms in a code block for reference.

Finally, ensure that all sections are properly formatted with markdown syntax and that the document is easy to read.
