+# KaZoe::Settings Class Documentation
+
+## Overview
+The `KaZoe::Settings` class provides a robust system-wide configuration management solution. It allows reading and writing settings from configuration files with category support, type safety, and change notifications.
+
+## Features
+- Read settings from multiple configuration files
+- Support for different value types (string, int, double, boolean)
+- Category-based organization of settings
+- File change monitoring
+- Permission-based write access
+- Change notification system
+
+## Configuration File Structure
+Settings are stored in configuration files with the `.conf` extension. The file format supports:
+- Categories in square brackets: `[CategoryName]`
+- Key-value pairs: `key = value`
+- Owner declarations: `@key = owner_id`
+
+### Value Types SettingValue
+- Strings: `key = "value"` or `key = value`
+- Numbers: `key = 42` or `key = 3.14`
+- Booleans: `key = true/false` or `key = on/off`
+
+## Usage
+
+### Initialization
+```cmake
+find_package(KaZoeSettings REQUIRED)
+include_directories(${LIBKAZOESETTINGS_INCLUDE_DIR})
+
+...
+
+target_link_libraries(myproject PUBLIC ${LIBKAZOESETTINGS_LIBRARIES})
+```
+
+```cpp
+#include <settings.h>
+
+KaZoe::Settings settings;  // Creates instance and loads configuration
+```
+
+### Reading Settings
+```cpp
+// Get value with default
+auto value = settings.get("key", "category", defaultValue);
+
+// Get value without category
+auto value = settings.get("key");
+
+// Get value using category notation
+auto value = settings.get("[category]key");
+```
+
+### Writing Settings
+```cpp
+// Set value with category
+settings.set("key", value, "category");
+
+// Set value without category
+settings.set("key", value);
+```
+
+### Utility with SettingValue type
+
+KaZoe::makeValue: provide a way to convert std::string into SettingValue managing numeric, bool and string conversion
+
+```cpp
+#include <settings.h>
+
+SettingValue v1 = KaZoe::makeValue("42");      // Integer
+SettingValue v2 = KaZoe::makeValue("3.14");    // Double
+SettingValue v3 = KaZoe::makeValue("true");    // Boolean
+SettingValue v4 = KaZoe::makeValue("text");    // String
+```
+
+KaZoe::valueToStr: provide a way to convert SettingValue into std::string to display
+```cpp
+#include <settings.h>
+
+std::cout << KaZoe::valueToStr(v1) << std::endl;
+```
+
+### Change Notifications and print helper function
+```cpp
+// Set a notification handler
+settings.setNotifier([](const std::string& category, const std::string& key, SettingValue value) {
+    // Handle setting change
+    std::cout << category << " | " << key << " changed to " << KaZoe::valueToStr(value) << std::endl;
+});
+```
+
+## File Locations
+The system reads configuration from:
+
+ - /etc/kazoe.conf - System defaults (read-only)
+ - /etc/kazoe.conf.d/* - System configuration fragments (read-only, own by projects packages)
+ - /var/kazoe.conf.d/<appid>.conf - Persistant write data storage (set)
+
+## Permissions
+
+Settings must be declared writable using @key = owner_id
+The owner should be the binary filename of the application
+Only the declared owner can modify the setting if the program name is the good one
+
+
+The settings command-line tool can bypass ownership restrictions but must used ONLY for debug usage
+
+## Value Types
+The system supports these value types through the SettingValue variant:
+
+ - std::string
+ - int
+ - double
+ - bool
+
+# KaZoeSettings Python Module Documentation
+## Overview
+
+The KaZoeSettings module provides a Python interface for managing KaZoe settings across your application. It automatically uses the Python script name as a unique identifier.
+
+## Usage Class: KaZoeSettings
+
+```python
+from KaZoeSettings import KaZoeSettings
+```
+
+## Constructor
+```python
+settings = KaZoeSettings.KaZoeSettings()
+```
+
+Creates a new KaZoeSettings instance using the current Python script name as identifier.
+
+## Methods
+
+### get(key, category="", default=None)
+
+Retrieves a setting value.
+
+    Parameters:
+        key (str): The setting key
+        category (str, optional): Setting category
+        default: Default value if setting not found
+    Returns: The setting value or default if not found
+    Supported value types: str, int, float, bool
+
+```python
+value = settings.get("my_setting", "my_category", "default_value")
+```
+
+### set(key, value, category="")
+
+Sets a setting value.
+
+    Parameters:
+        key (str): The setting key
+        value: The value to set (str, int, float, or bool)
+        category (str, optional): Setting category
+    Returns: True if successful, False otherwise
+
+```python
+settings.set("my_setting", "new_value", "my_category")
+```
+
+## Full example usage
+
+```python
+from KaZoeSettings import KaZoeSettings
+
+# Create settings instance
+settings = KaZoeSettings()
+
+# Set values
+settings.set("port", 8080, "network")
+settings.set("debug", True, "app")
+
+# Get values
+port = settings.get("port", "network", 80)  # returns 8080
+debug = settings.get("debug", "app", False)  # returns True
+```
