+  <img width="824" alt="Ollama Settings" src="https://github.com/user-attachments/assets/ed64e03a-a923-467a-aa44-4f790e315b53" />
+</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
+

-## Installation Plugin
+## Hotkeys
 
-1. Install QtCreator 14.0
-2. Install [Ollama](https://ollama.com). Make sure to review the system requirements before installation.
-3. Install a language model in Ollama. For example, you can run:
-```
-ollama run starcoder2:7b
-```
-4. Download the QodeAssist plugin.
-5. Launch Qt Creator and install the plugin:
-   - Go to About -> About Plugins
-   - Click on "Install Plugin..."
-   - Select the downloaded QodeAssist plugin archive file
+- To call manual request to suggestion, you can use or change it in settings
+    - on Mac: Option + Command + Q
+    - on Windows: Ctrl + Alt + Q
+- To insert the full suggestion, you can use the TAB key
+- To insert word of suggistion, you can use Alt + Right Arrow for Win/Lin, or Option + Right Arrow for Mac
+    
+## Troubleshooting
 
-## Configure Plugin
+If QodeAssist is having problems connecting to the LLM provider, please check the following:
 
+1. Verify the IP address and port:
+
+    - For Ollama, the default is usually http://localhost:11434
+    - For LM Studio, the default is usually http://localhost:1234
+
+2. Check the endpoint:
+
+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. 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
-
-You're all set! QodeAssist is now ready to use in Qt Creator.
+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
