+## Configure Plugin
+
+QodeAssist comes with default settings that should work immediately after installing a language model. The plugin is pre-configured to use Ollama with standard templates, so you may only need to verify the settings.
+
+1. Open Qt Creator settings (Edit > Preferences on Linux/Windows, Qt Creator > Preferences on macOS)
+2. Navigate to the "Qode Assist" 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
+4. Click Apply if you made any changes
+
+You're all set! QodeAssist is now ready to use in Qt Creator.
 
 ## Supported LLM Providers
 QodeAssist currently supports the following LLM (Large Language Model) providers:
 - [Ollama](https://ollama.com)
 - [LM Studio](https://lmstudio.ai)
+- [OpenRouter](https://openrouter.ai)
+- OpenAI compatible providers
 
-## Supported Models
-QodeAssist has been tested with the following language models:
+## Recommended Models:
+QodeAssist has been thoroughly tested and optimized for use with the following language models:
 
-Ollama:
-- [starcoder2](https://ollama.com/library/starcoder2)
-- [codellama](https://ollama.com/library/codellama)
+- Qwen2.5-coder
+- CodeLlama
+- StarCoder2
+- DeepSeek-Coder-V2
 
-LM studio:
-- [second-state/StarCoder2-7B-GGUF](https://huggingface.co/second-state/StarCoder2-7B-GGUF)
-- [TheBloke/CodeLlama-7B-GGUF](https://huggingface.co/TheBloke/CodeLlama-7B-GGUF)
+### Model Types
 
-Please note that while these models have been specifically tested and confirmed to work well with QodeAssist, other models compatible with the supported providers may also work. We encourage users to experiment with different models and report their experiences.
-If you've successfully used a model that's not listed here, please let us know by opening an issue or submitting a pull request to update this list.
+FIM models (codellama:7b-code, starcoder2:7b, etc.) - Optimized for code completion and suggestions
+
+Instruct models (codellama:7b-instruct, starcoder2:instruct, etc.) - Better for chat assistance, explanations, and code review
+
+For best results, use FIM models with code completion and Instruct models with chat features.
+
+### Ollama:
+### For autocomplete(FIM)
+```
+ollama run codellama:7b-code
+ollama run starcoder2:7b
+ollama run qwen2.5-coder:7b-base
+ollama run deepseek-coder-v2:16b-lite-base-q3_K_M
+```
+### For chat and instruct
+```
+ollama run codellama:7b-instruct
+ollama run starcoder2:instruct
+ollama run qwen2.5-coder:7b-instruct
+ollama run deepseek-coder-v2
+```
+
+### Template-Model Compatibility
+
+| Template | Compatible Models | Purpose |
+|----------|------------------|----------|
+| CodeLlama FIM | `codellama:code` | Code completion |
+| DeepSeekCoder FIM | `deepseek-coder-v2`, `deepseek-v2.5` | Code completion |
+| Ollama Auto FIM | `Any Ollama base model` | Code completion |
+| Qwen FIM | `Qwen 2.5 models` | Code completion |
+| StarCoder2 FIM | `starcoder2 base model` | Code completion |
+| Alpaca | `starcoder2:instruct` | Chat assistance |
+| Basic Chat| `Messages without tokens` | Chat assistance |
+| ChatML | `Qwen 2.5 models` | Chat assistance |
+| Llama2 | `llama2 model family`, `codellama:instruct` | Chat assistance |
+| Llama3 | `llama3 model family` | Chat assistance |
+| Ollama Auto Chat | `Any Ollama chat model` | Chat assistance |
+
+> Note: 
+> - FIM (Fill-in-Middle) templates are optimized for code completion
+> - Chat templates are designed for interactive dialogue
+> - The Ollama Auto templates automatically adapt to most Ollama models
+> - Custom Template allows you to define your own prompt format
+
+## QtCreator Version Compatibility
+
+- QtCreator 15.0.0 - 0.4.x 
+- QtCreator 14.0.2 - 0.2.3 - 0.3.x 
+- QtCreator 14.0.1 - 0.2.2 plugin version and below
 
 ## Development Progress
 
 - [x] Basic plugin with code autocomplete functionality
-- [ ] Improve and automate settings
-- [ ] Add chat functionality
+- [x] Improve and automate settings
+- [x] Add chat functionality
+- [x] Sharing diff with model
+- [ ] Sharing project source with model
 - [ ] Support for more providers and models
 
-## 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
