+</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 Feature
+
+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
+
+## Quick Refactoring Feature
+### Setup
+  Since this is actually a small chat with redirected output, the main settings of the provider, model and template are taken from the chat settings
+### Using
+  The request to model consist of instructions to model, selection code and cursor position
+  The default instruction is: "Refactor the code to improve its quality and maintainability." and sending if text field is empty
+  Also there buttons to quick call instractions:
+  * Repeat latest instruction, will activate after sending first request in QtCreator session
+  * Improve current selection code
+  * Suggestion alternative variant of selection code
+  * Other instructions[TBD]

 ## Hotkeys
 
 - To call manual request to suggestion, you can use or change it in settings
     - on Mac: Option + Command + Q
     - on Windows: Ctrl + Alt + Q
+    - on Linux with KDE Plasma: Ctrl + Alt + Q
 - To insert the full suggestion, you can use the TAB key
-- To insert line by line, you can use the "Move cursor word right" shortcut:
-    - On Mac: Option + Right Arrow
-    - On Windows: Alt + Right Arrow
+- To insert word of suggistion, you can use Alt + Right Arrow for Win/Lin, or Option + Right Arrow for Mac

+    - on Mac: Option + Command + R
+    - on Windows: Ctrl + Alt + R
+    - on Linux with KDE Plasma: Ctrl + Alt + R
+
+## Ignoring Files
+QodeAssist supports the ability to ignore files in context using a .qodeassistignore file. This allows you to exclude specific files from the context during code completion and in the chat assistant, which is especially useful for large projects.
+
+### How to Use .qodeassistignore
+- Create a .qodeassistignore file in the root directory of your project near CMakeLists.txt or pro.
+- Add patterns for files and directories that should be excluded from the context.
+- QodeAssist will automatically detect this file and apply the exclusion rules.
+
+### .qodeassistignore File Format
+The file format is similar to .gitignore:
+- Each pattern is written on a separate line
+- Empty lines are ignored
+- Lines starting with # are considered comments
+- Standard wildcards work the same as in .gitignore
+- To negate a pattern, use ! at the beginning of the line
+```
+# Ignore all files in the build directory
+/build
+*.tmp
+# Ignore a specific file
+src/generated/autogen.cpp
+
+```
