+## System Prompt Configuration
 
-## Supported LLM Providers
-QodeAssist currently supports the following LLM (Large Language Model) providers:
-- [Ollama](https://ollama.com)
-- [LM Studio](https://lmstudio.ai)
-- OpenAI compatible providers
+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.
 
-## Recommended Models:
-QodeAssist has been thoroughly tested and optimized for use with the following language models:
+## File Context Features
 
-- Llama
-- CodeLlama
-- StarCoder2
-- DeepSeek-Coder-V2
-- Qwen-2.5
+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.
 
-### 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
-```
-ollama run codellama:7b-instruct
-ollama run starcoder2:instruct
-ollama run qwen2.5-coder:7b-instruct
-ollama run deepseek-coder-v2
-```
+### Attached Files
 
-### LM Studio:
-   similar models, like for ollama
+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
 
-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.
+### Linked Files
 
-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.
+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
