+
+## Install plugin to QtCreator
+
+### Method 1: Using QodeAssistUpdater (Beta)
+
+QodeAssistUpdater is a command-line utility that automates plugin installation and updates with automatic Qt Creator version detection and checksum verification.
+
+**Features:**
+- Automatic Qt Creator version detection
+- Install, update, or remove plugin with single command
+- List all available plugin versions
+- Install specific plugin version
+- Checksum verification
+- Non-interactive mode for CI/CD
+
+**Installation:**
+
+Download pre-built binary from [QodeAssistUpdater releases](https://github.com/Palm1r/QodeAssistUpdater/releases) or build from source
+
+**Usage:**
+
+```bash
+# Check current status and available updates
+./qodeassist-updater --status
+
+# Install latest version
+./qodeassist-updater --install
 ```
-ollama run starcoder2:7b
-```
-4. Download the QodeAssist plugin.
-5. Launch Qt Creator and install the plugin:
-   - Go to About -> About Plugins
+
+For more information, visit the [QodeAssistUpdater repository](https://github.com/Palm1r/QodeAssistUpdater).
+
+### Method 2: Manual Installation
+
+1. Install Latest Qt Creator
+2. Download the QodeAssist plugin for your Qt Creator
+   - Remove old version plugin if already was installed
+      - on macOS for QtCreator 16: ~/Library/Application Support/QtProject/Qt Creator/plugins/16.0.0/petrmironychev.qodeassist
+      - on windows for QtCreator 16: C:\Users\<user>\AppData\Local\QtProject\qtcreator\plugins\16.0.0\petrmironychev.qodeassist\lib\qtcreator\plugins  
+3. Launch Qt Creator and install the plugin:
+   - Go to: 
+     - MacOS: Qt Creator -> About Plugins...
+     - Windows\Linux: Help -> About Plugins...
    - Click on "Install Plugin..."
    - Select the downloaded QodeAssist plugin archive file
 
-## Configure Plugin
+## Configuration
 
-1. Open Qt Creator settings
-2. Navigate to the "Qode Assist" tab
-3. Choose your LLM provider (e.g., Ollama)
-   - If you haven't added the provider to your system PATH, specify the path to the provider executable in the "Provider Paths" field
-4. Select the installed model
-   - If you need to enter the model name manually, it indicates that the plugin cannot locate the provider's executable file. However, this doesn't affect the plugin's functionality – it will still work correctly. This autoselector input option is provided for your convenience, allowing you to easily select and use different models
-5. Choose the prompt template that corresponds to your model
-6. Apply the settings
+QodeAssist supports multiple LLM providers. Choose your preferred provider and follow the configuration guide:
 
-You're all set! QodeAssist is now ready to use in Qt Creator.
+### Supported Providers
+
+- **[Ollama](docs/ollama-configuration.md)** - Local LLM provider
+- **[llama.cpp](docs/llamacpp-configuration.md)** - Local LLM server
+- **[Anthropic Claude](docs/claude-configuration.md)** - Сloud provider
+- **[OpenAI](docs/openai-configuration.md)** - Сloud provider
+- **[Mistral AI](docs/mistral-configuration.md)** - Сloud provider
+- **[Google AI](docs/google-ai-configuration.md)** - Сloud provider
+- **LM Studio** - Local LLM provider
+- **OpenAI-compatible** - Custom providers (OpenRouter, etc.)
+
+### Additional Configuration
+
+- **[Project Rules](docs/project-rules.md)** - Customize AI behavior for your project
+- **[Ignoring Files](docs/ignoring-files.md)** - Exclude files from context using `.qodeassistignore`
+
+## Features
+
+### Code Completion
+- AI-powered intelligent code completion
+- Support for C++ and QML
+- Context-aware suggestions
+- Multiline completions
+
+#### Completion Trigger Modes
+
+QodeAssist offers two trigger modes for code completion:
+
+**Hint-based (Default, Recommended)**
+- Shows a hint indicator near cursor when you type 3+ characters
+- Press **Space** (or custom key) to request completion
+- **Best for**: Paid APIs (Claude, OpenAI), conscious control
+- **Benefits**: No unexpected API charges, full control over requests, no workflow interruption
+- **Visual**: Clear indicator shows when completion is ready
+
+**Automatic**
+- Automatically requests completion after typing threshold
+- Works immediately without additional keypresses
+- **Best for**: Local models (Ollama, llama.cpp), maximum automation
+- **Benefits**: Hands-free experience, instant suggestions
+
+💡 **Tip**: Start with Hint-based to avoid unexpected costs. Switch to Automatic if using free local models.
+
+Configure in: `Tools → Options → QodeAssist → Code Completion → General Settings`
+
+### Chat Assistant
+- Multiple chat panels: side panel, bottom panel, and popup window
+- Chat history with auto-save and restore
+- Token usage monitoring
+- **[File Context](docs/file-context.md)** - Attach or link files for better context
+- Automatic syncing with open editor files (optional)
+- Extended thinking mode (Claude, other providers in plan) - Enable deeper reasoning for complex tasks
+
+### Quick Refactoring
+- Inline code refactoring directly in the editor with AI assistance
+- Selection-based improvements with instant code replacement
+- Built-in quick actions (repeat, improve, alternative)
+- **Custom instructions library** with search and autocomplete
+- Create, edit, and manage reusable refactoring templates
+- Combine base instructions with specific details
+- **[Learn more](docs/quick-refactoring.md)**
+
+### Tools & Function Calling
+- Read project files
+- List and search in project
+- Access linter/compiler issues
+- Enabled by default (can be disabled)
+
+## Context Layers
+
+QodeAssist uses a flexible prompt composition system that adapts to different contexts. Here's how prompts are constructed for each feature:

+
+### 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.

+### Build Steps
+
+1. Create a build directory:
+
+```bash
+mkdir build && cd build
+```
+
+2. Configure and build:
+
+```bash
+cmake -DCMAKE_PREFIX_PATH=<path_to_qtcreator> -DCMAKE_BUILD_TYPE=RelWithDebInfo <path_to_plugin_source>
+cmake --build .
+```
+
+**Path specifications:**
+- `<path_to_qtcreator>`:
+  - **Windows/Linux**: Qt Creator build directory or combined binary package
+  - **macOS**: `Qt Creator.app/Contents/Resources/`
+- `<path_to_plugin_source>`: Path to this plugin directory
+
+## For Contributors
