LLM Practical Skills Treasure Trove: A Complete Guide from Prompt Engineering to Local Deployment

This article introduces the GitHub open-source repository llm-queries (by author djeada, released on June 16, 2026). It is a systematic collection of LLM practical resources covering prompt templates, local deployment guides, RAG implementation, AI agent construction, and other practical content, helping developers efficiently utilize large language models. The repository adopts a modular structure, suitable for users of different levels to access on demand. Its core lies in providing a complete methodology from basics to advanced levels, making conversations with LLMs a learnable and improvable skill.

In LLM applications, Prompt Engineering often determines output quality—well-designed prompts can make ordinary models produce professional results, while poor prompts can make advanced models perform unsatisfactorily. This repository was created precisely to solve this problem; it is not just a collection of prompts, but a complete methodology for using LLMs, covering all aspects from basic text processing to complex AI agent construction. Repository source: Author djeada, released on GitHub with the original title "llm-queries: Practical Tips for Getting the Most Out of GPT and Other Large Language Models" on June 16, 2026.

The repository uses a clear modular structure, with core sections including:

1. Prompt Template Library (prompts/): Contains battle-tested templates such as text processing (polishing, formatting), job search (resume optimization, interview question generation), social media (title generation), etc., with clear input/output formats and effect descriptions;
2. Local Deployment Guides (local_setup_guides/): The introductory guide explains the installation and use of the Ollama tool (which can run open-source models like Llama and DeepSeek), while the advanced guide covers configuration optimization for the DeepSeek R1 inference model;
3. Learning Resources and Course Notes: Organizes key points of official best practices from OpenAI and Anthropic, and includes notes from Anthropic's prompt engineering course and Hugging Face's LLM introduction, etc.;
4. Teaching Slides (slides/): Markdown-formatted materials covering topics such as LLM basics, Transformer architecture, RAG, and vector databases.

The article polishing prompt example in the repository demonstrates the power of structured prompts: The original input is "Caching can improve website performance", and after being guided by the prompt, the model output expands to:

Caching speeds up websites by storing frequently accessed data, so the server doesn't need to rebuild the same response every time. The result is faster page loading for users and less workload for the backend during traffic peaks. This example shows that a good prompt not only tells the model what to do but also guides how to do it (adding examples, correcting errors, using straightforward language).

Efficient use of LLMs requires systematic knowledge and tool support. This open-source repository provides one-stop LLM practical resources through structured prompt templates, local deployment guides, learning resources, and teaching materials. Whether you are a novice or an experienced user, you can find valuable content. The key point is: Conversations with LLMs are a learnable and improvable skill, not a black-box operation relying on intuition.

The repository author emphasizes the following usage principles:

1. Test Different Models: The same prompt performs very differently on models like GPT-4, Claude, and Llama, so adjustments are needed according to needs;
2. Iterative Optimization: Start with a basic version and continuously adjust the prompt based on output;
3. Combined Use: Complex tasks require multiple prompts to be connected in series (e.g., first extract information then format it);
4. Record Variants: Maintain personal prompt notes, record effective variants, and build a knowledge base.

The repository content adapts to users of different levels:

• Beginners: Start with the LLM basic slides, learn basic prompt skills, and try simple text processing;
• Practitioners: Consult official guides, configure the local model environment, and research AI agent construction;
• Educators: Use ready-made teaching slides and the glossary (GLOSSARY.md) to save lesson preparation time.

As an open-source project, the repository welcomes community contributions, including adding new prompt templates, expanding course notes, improving documentation, and supplementing model compatibility descriptions. The open model ensures that the content keeps up with the rapid development of the LLM field. This repository is more like a toolbox—users can quickly find solutions when encountering specific problems.
