 ## Overview
 
-**OPTIMA-35** (**Organizing, Processing, Tweaking Images and Modifying scanned Analogs from 35mm Film**) is a Python-based project designed to provide a streamlined way to manage and edit metadata and images from analog photography. But can be used for any images.
+**OPTIMA-35** (**Organizing, Processing, Tweaking Images, and Modifying scanned Analogs from 35mm Film**) is a Python-based project designed to streamline the management and editing of metadata and images from analog photography. While it was created with analog photography in mind, it is versatile enough to handle any type of images.
 
-This project is a *port* of my earlier work, an collection of [bash script](https://gitlab.com/sf-bashscripts/analogphotography), transitioning functionality to a more modular and maintainable design.
+This project replaces my earlier [analogphotography](https://gitlab.com/sf-bashscripts/analogphotography) bash script collection, which has now been archived in favor of OPTIMA-35.
 
-**Please check** if a new branch is available and read the **changelog** to see the progress and current features of the program. The README might sometimes lag behind.
-
-OPTIMA-35 is evolving! The project is transitioning from a terminal-based user interface (TUI) to a graphical user interface (GUI) using Qt (via PySide6). First TUI version was forked to [OPTIMA-35 TUI](https://gitlab.com/python_projects3802849/optima-35-tui). I intend to keep the TUI version functional since it is usefull for headless setup.

-
-*Last preview until GUI is finished.*
+**OPTIMA-35** is a cross-platform program. The **GUI** works on Linux and Windows (tested) and is expected to run on macOS. The **TUI** is currently Linux-only, as its dependency is exclusive to Linux.

-## **Current Status**
-**The README is temporarily outdated** while the GUI version is under development. For the latest updates, please check the **changelog**—I always maintain a detailed log of changes.
+## Current Status
+
+### PLEASE NOTE
+The project is under active development. As a result:
+- The README may sometimes be outdated.
+- I encourage you to check for new branches and read the **CHANGELOG**, which is consistently updated and well-documented.
+- Bugs or unforeseen behavior may occur.
+
+**OPTIMA-35** supports two modes: **GUI** and **TUI**.
+- The **GUI** is loaded by default if **PySide6** is available.
+- The **TUI** serves as a fallback when **PySide6** is unavailable or can be started explicitly using the `--tui` option with `main.py`.
+
+While all features are implemented and functional, the designs of both the GUI and TUI are not yet finalized. Some safety checks are still under development.

 ## Dependencies
 
-To run **OPTIMA-35**, the following Python libraries are required:
+**OPTIMA-35** has two modes: **GUI** and **TUI**. Each mode has its own set of dependencies, so you don’t need to install TUI dependencies if you only plan to use the GUI (and vice versa).
 
-- **pyyaml**: To handle YAML files for configuration and settings.
-- **piexif**: To read, modify, and write EXIF metadata.
-- **Pillow**: For image processing.
-- **pyside6**: GUI
+**Required Dependencies:**
+- **pyyaml**: For handling YAML files (configuration and settings).
+- **piexif**: For reading, modifying, and writing EXIF metadata.
+- **pillow**: For image processing.
+- **pyside6**: For the GUI mode.
+- **simple_term_menu**: For the TUI mode.
 
 ### Installing Dependencies
 
-You can install the dependencies using `pip`:
+You can install the dependencies using the respective requirements file for your desired mode (**TUI** or **GUI**).
 
+Using `pip`:
 ```bash
-pip install -r requirements.txt
+pip install -r requirements_gui.txt
 ```
 
-Alternatively, you can use `conda` or its alternatives (`anaconda`, `mamba`, `micromamba`):
