-QodeAssist is an AI-powered coding assistant plugin for Qt Creator. It provides intelligent code completion and suggestions for C++ and QML, leveraging large language models through local providers like Ollama. Enhance your coding productivity with context-aware AI assistance directly in your Qt development environment.
+![qodeassist-icon](https://github.com/user-attachments/assets/dc336712-83cb-440d-8761-8d0a31de898d) QodeAssist is a comprehensive AI-powered coding assistant plugin for Qt Creator. It provides intelligent code completion, interactive chat with multiple interface options, inline quick refactoring, and AI function calling capabilities for C++ and QML development. Supporting both local providers (Ollama, llama.cpp, LM Studio) and cloud services (Claude, OpenAI, Google AI, Mistral AI), QodeAssist enhances your productivity with context-aware AI assistance, project-specific rules, and extensive customization options directly in your Qt development environment.

-## Supported Models
+## Overview
 
-QodeAssist has been thoroughly tested and optimized for use with the following language models, all of which are specifically trained for Fill-in-the-Middle (FIM) tasks:
+QodeAssist enhances Qt Creator with AI-powered coding assistance:
 
-- CodeLlama
-- StarCoder2
-- DeepSeek-Coder-V2-Lite-Base
+- **Code Completion**: Intelligent, context-aware code suggestions for C++ and QML
+- **Chat Assistant**: Multiple interface options (popup window, side panel, bottom panel)
+- **Quick Refactoring**: Inline AI-assisted code improvements directly in editor with custom instructions library
+- **File Context**: Attach or link files for better AI understanding
+- **Tool Calling**: AI can read project files, search code, and access diagnostics
+- **Multiple Providers**: Support for Ollama, Claude, OpenAI, Google AI, Mistral AI, llama.cpp, and more
+- **Customizable**: Project-specific rules, custom instructions, and extensive model templates
 
-These models have demonstrated excellent performance in code completion and assistance tasks within the QodeAssist environment.

+## Install plugin to QtCreator
 
-Please note that while these models have been specifically tested and confirmed to work well with QodeAssist, other models compatible with the supported providers may also work. We encourage users to experiment with different models and report their experiences.
+### Method 1: Using QodeAssistUpdater (Beta)
 
-If you've successfully used a model that's not listed here, please let us know by opening an issue or submitting a pull request to update this list.
+QodeAssistUpdater is a command-line utility that automates plugin installation and updates with automatic Qt Creator version detection and checksum verification.
 
-## Development Progress

+
+### Key Points
+
+- **Project Rules** are automatically loaded from `.qodeassist/rules/` directory structure
+- **System Prompts** are configured independently for each feature in Settings
+- **FIM vs Non-FIM models** for code completion use different System Prompts:
+  - FIM models: Direct completion prompt
+  - Non-FIM models: Prompt includes response formatting instructions
+- **Quick Refactor** has its own provider/model configuration, independent from Chat
+- **Custom Instructions** provide reusable templates that can be augmented with specific details
+- **Tool Calling** is available for Chat and Quick Refactor when enabled
+
+See [Project Rules Documentation](docs/project-rules.md) and [Quick Refactoring Guide](docs/quick-refactoring.md) for more details.

-    - on Mac: Option + Command + Q
-    - on Windows: Ctrl + Alt + Q
-- To insert the full suggestion, you can use the TAB key
-- To insert line by line, you can use the "Move cursor word right" shortcut:
-    - On Mac: Option + Right Arrow
-    - On Windows: Alt + Right Arrow
+All hotkeys can be customized in Qt Creator Settings. Default hotkeys:
+
+| Action | macOS | Windows/Linux |
+|--------|-------|--------------|
+| Open chat window | ⌥⌘W | Ctrl+Alt+W |
+| Close chat window | ⌥⌘S | Ctrl+Alt+S |

 ## Troubleshooting
 
-If QodeAssist is having problems connecting to the LLM provider, please check the following:
+Having issues with QodeAssist? Check our [detailed troubleshooting guide](docs/troubleshooting.md) for:
 
-1. Verify the IP address and port:
+- Connection issues and provider URLs
+- Model and template compatibility
+- Platform-specific issues (Linux, macOS, Windows)
+- Resetting settings to defaults
+- Common problems and solutions
 
-    - For Ollama, the default is usually http://localhost:11434
-    - For LM Studio, the default is usually http://localhost:1234
+For additional support, join our [Discord Community](https://discord.gg/BGMkUsXUgf) or check [GitHub Issues](https://github.com/Palm1r/QodeAssist/issues).
 
-2. Check the endpoint:
+## Development Progress
 
-Make sure the endpoint in the settings matches the one required by your provider
-    - For Ollama, it should be /api/generate
-    - For LM Studio and OpenAI compatible providers, it's usually /v1/chat/completions
-
-3. Confirm that the selected model and template are compatible:
-
-Ensure you've chosen the correct model in the "Select Models" option
-Verify that the selected prompt template matches the model you're using
-
-If you're still experiencing issues with QodeAssist, you can try resetting the settings to their default values:
-1. Open Qt Creator settings
-2. Navigate to the "Qode Assist" tab
-3. Pick settings page for reset
-4. Click on the "Reset Page to Defaults" button
-    - The API key will not reset
-    - Select model after reset
