-## Configure for Ollama
+### Additional Configuration
 
-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:
+- **[Project Rules](docs/project-rules.md)** - Customize AI behavior for your project
+- **[Ignoring Files](docs/ignoring-files.md)** - Exclude files from context using `.qodeassistignore`
 
-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
-```

-## 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)

+### Quick Refactoring
+- Fast code refactoring with AI assistance
+- Selection-based improvements
+- Alternative code suggestions
+- **[Learn more](docs/quick-refactoring.md)**
 
-## 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
+### Tools & Function Calling
+- Read project files
+- List and search in project
+- Access linter/compiler issues
+- Enabled by default (can be disabled)

 ## 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. Confirm that the selected model and template are compatible:
+## Development Progress
 
-    Ensure you've chosen the correct model in the "Select Models" option
-    Verify that the selected prompt template matches the model you're using
-
-3. On Linux the prebuilt binaries support only ubuntu 22.04+ or simililliar os. 
-If you need compatiblity with another os, you have to build manualy. our experiments and resolution you can check here: https://github.com/Palm1r/QodeAssist/issues/48
-
-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
+- [x] Code completion functionality
+- [x] Chat assistant with multiple panels
+- [x] Diff sharing with models
+- [x] Tools/function calling support
+- [x] Project-specific rules
+- [ ] Full project source sharing

-where `<path_to_qtcreator>` is the relative or absolute path to a Qt Creator build directory, or to a
-combined binary and development package (Windows / Linux), or to the `Qt Creator.app/Contents/Resources/`
-directory of a combined binary and development package (macOS), and `<path_to_plugin_source>` is the
-relative or absolute path to this plugin directory.
+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 .
+```
+
