 # OCR4Linux
 
-OCR4Linux is a tool that allows you to take a screenshot of a selected area, extract the text from the image, and copy it to the clipboard. It supports both Wayland and X11 sessions and uses various tools to achieve its functionality.
-Note: This script is currently only made for Arch Linux. It may work on other arch-based distributions, but it has not been tested yet.
+OCR4Linux is a versatile text extraction tool that allows you to take a screenshot of a selected area, extract text using OCR, and copy it to the clipboard. It supports both Wayland and X11 sessions and offers multiple language support.
+
+**Note:** This script is currently only made for Arch Linux. It may work on other arch-based distributions, but it has not been tested yet.
 
 ## Motivation
 
 I didn't find any easy tool in Linux that does the same thing as the PowerTool app in Windows. This motivated me to create OCR4Linux, a simple and efficient tool to capture screenshots, extract text, and copy it to the clipboard, all in one seamless process.
 
 ## Features
 
--   Takes screenshots using `grimblast` for Wayland and `scrot` for X11.
--   Uses a pytesseract python script to preprocess the image and extract text.
--   Copies the extracted text to the clipboard using `wl-copy` and `cliphist` for Wayland and `xclip` for X11.
+-   **Screenshot Capture**
+
+    -   Wayland support via `grimblast`
+    -   X11 support via `scrot`
+    -   Configurable screenshot directory
+
+-   **Text Extraction**
+
+    -   Automatic language detection
+    -   Multi-language OCR support
+    -   Image preprocessing for better accuracy
+    -   UTF-8 text output
+
+-   **Clipboard Integration**
+
+    -   Wayland: `wl-copy` and `cliphist`
+    -   X11: `xclip`
+
+-   **Additional Features**
+    -   Optional screenshot retention
+    -   Comprehensive logging system
+    -   Command-line interface
 
 ## Requirements

 ## Tips
 
--   You can customize the script to suit your needs by changing the screenshot tool, text extraction method, or clipboard manager.
 -   You can create a keyboard shortcut to run the script for easy access.
     ### Example for `Hyprland` users:
     -   put the following lines in your `hyprland.conf` file:
-        ```
+        ```conf
         $OCR4Linux = ~/.config/OCR4Linux/OCR4Linux.sh
         bind = $mainMod SHIFT, E, exec, $OCR4Linux # OCR4Linux script
         ```
     ### Example for `dwm` users:
     -   put the following lines in your `config.h` file:
-        ```
+        ```c
         static const char *ocr4linux[] = { "sh", "-c", "~/.config/OCR4Linux/OCR4Linux.sh", NULL };
-        { MODKEY | ShiftMask, XK_e, spawn, {.v = ocr4linux } }, // OCR4Linux script
+        { MODKEY | ShiftMask, XK_e, spawn, {.v = ocr4linux } },  // OCR4Linux script
