-## Configure for Ollama
-
-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

-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
+</details>
 
-### Linked Files
+### Key Points
 
-Linked files provide persistent context throughout the conversation:
+- **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
 
-  - 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
+See [Project Rules Documentation](docs/project-rules.md) and [Quick Refactoring Guide](docs/quick-refactoring.md) for more details.

 ## 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

-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>
