-## Recommended Models:
-QodeAssist has been thoroughly tested and optimized for use with the following language models:
+## System Prompt Configuration
 
-- Qwen2.5-coder
-- CodeLlama
-- StarCoder2
-- DeepSeek-Coder-V2
+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.
 
-### 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
-```
+## File Context Features
 
-### Template-Model Compatibility
+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.
 
-| 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 |

+### Attached Files
 
-> 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
+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
