+  - Quick refactor code via fast chat command and opened files
+- Chat functionality:
+  - Side and Bottom panels
+  - Chat history autosave and restore
+  - Token usage monitoring and management
+  - Attach files for one-time code analysis
+  - Link files for persistent context with auto update in conversations
+  - Automatic syncing with open editor files (optional)
+- Support for multiple LLM providers:
+  - Ollama
+  - llama.cpp
+  - OpenAI
+  - Anthropic Claude
+  - LM Studio
+  - Mistral AI
+  - Google AI
+  - OpenAI-compatible providers(eg. llama.cpp, https://openrouter.ai)

+1. Install [Ollama](https://ollama.com). Make sure to review the system requirements before installation.
+2. Install a language models in Ollama via terminal. For example, you can run:
+
+For standard computers (minimum 8GB RAM):
+```
+ollama run qwen2.5-coder:7b
+```
+For better performance (16GB+ RAM):
+```
+ollama run qwen2.5-coder:14b
+```
+For high-end systems (32GB+ RAM):
+```
+ollama run qwen2.5-coder:32b
+```
+
+1. Open Qt Creator settings (Edit > Preferences on Linux/Windows, Qt Creator > Preferences on macOS)
+2. Navigate to the "QodeAssist" tab
+3. On the "General" page, verify:
+    - Ollama is selected as your LLM provider
+    - The URL is set to http://localhost:11434
+    - Your installed model appears in the model selection
+    - The prompt template is Ollama Auto FIM or Ollama Auto Chat for chat assistance. You can specify template if it is not work correct
+4. Click Apply if you made any changes
+
+You're all set! QodeAssist is now ready to use in Qt Creator.

+
+## Configure for llama.cpp
+1. Open Qt Creator settings and navigate to the QodeAssist section
+2. Go to General tab and configure:
+   - Set "llama.cpp" as the provider for code completion or/and chat assistant
+   - Set the llama.cpp URL (e.g. http://localhost:8080)
+   - Fill in model name
+   - Choose template for model(e.g. llama.cpp FIM for any model with FIM support)

+</details>
+
+## System Prompt Configuration
+
+The plugin comes with default system prompts optimized for chat and instruct models, as these currently provide better results for code assistance. If you prefer using FIM (Fill-in-Middle) models, you can easily customize the system prompt in the settings.
+
+## File Context Features
+
+QodeAssist provides two powerful ways to include source code files in your chat conversations: Attachments and Linked Files. Each serves a distinct purpose and helps provide better context for the AI assistant.
+
+### Attached Files
+
+Attachments are designed for one-time code analysis and specific queries:
+  - Files are included only in the current message
+  - Content is discarded after the message is processed
+  - Ideal for:
+    - Getting specific feedback on code changes
+    - Code review requests
+    - Analyzing isolated code segments
+    - Quick implementation questions
+  - Files can be attached using the paperclip icon in the chat interface
+  - Multiple files can be attached to a single message
+
+### Linked Files
+
+Linked files provide persistent context throughout the conversation:
+
+  - Files remain accessible for the entire chat session
+  - Content is included in every message exchange
+  - Files are automatically refreshed - always using latest content from disk
+  - Perfect for:
+    - Long-term refactoring discussions
+    - Complex architectural changes
+    - Multi-file implementations
+    - Maintaining context across related questions
+  - Can be managed using the link icon in the chat interface
+  - Supports automatic syncing with open editor files (can be enabled in settings)
+  - Files can be added/removed at any time during the conversation
+
