 ## 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
+## Project Rules Configuration
+
+QodeAssist supports project-specific rules to customize AI behavior for your codebase. Create a `.qodeassist/rules/` directory in your project root.
+
+### Quick Start
+```bash
+mkdir -p .qodeassist/rules/{common,completion,chat,quickrefactor}
+```
+```
+.qodeassist/
+└── rules/
+    ├── common/           # Applied to all contexts
+    ├── completion/       # Code completion only
+    ├── chat/            # Chat assistant only
+    └── quickrefactor/   # Quick refactor only
+```
+All .md files in each directory are automatically loaded and added to the system prompt.
+
+Example
+Create .qodeassist/rules/common/general.md:
+```markdown
+# Project Guidelines
+- Use snake_case for private members
+- Prefix interfaces with 'I'
+- Always document public APIs
+- Prefer Qt containers over STL
+```
+
+## 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.

-| DeepSeekCoder FIM | `deepseek-coder-v2`, `deepseek-v2.5` | Code completion |

-| Ollama Auto Chat | `Any Ollama chat/instruct models` | Chat assistance |
+## 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]

+
+## 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
+
+```
