 ## Features
 - Validate XML files and detect parsing or formatting errors.  
 - Convert XML to JSON for easier data handling and storage.  
-- Compress and decompress XML files (CLI future feature).  
+- Compress and decompress XML files.
+- Pretty-print XML files for better readability.
+- Minify XML files to reduce storage space.
 - Simple GUI to load, format, and convert XML files. 
 - CLI flags for quick batch processing of XML files.
+- Analyze social media XML files and visualize the relationships between users and posts using graph analysis.
 
 ## Requirements
-- The [Mingw-w64](https://www.mingw-w64.org/) compiler (for Windows) or GCC (for Linux).
-- [CMake](https://cmake.org/) (version ≥ 3.19).  
-- [Qt6](https://www.qt.io/) if you want to build the GUI application.  
-- A build system (e.g., Ninja, Make, Visual Studio).
+- [Graphviz](https://graphviz.org/) must be installed for generating and drawing the graphs.
+- **Download and use the prebuilt Qt application from the GitHub Releases** instead of building from source for a quicker setup.
+- **Building from source** requires the following:
+  - CMake 3.19 or later.
+  - Qt6.
+  - A C++17-compatible compiler.
+  - Ninja (optional but recommended for faster builds).

 ## Quick Setup
 1. Clone this repository locally.  
 2. Ensure CMake and Qt6 are installed and available in your PATH.

 ## Usage
 ### CLI
 Use the CLI for automated or script-based workflows:
 ```shell
-    cli_app <command> -option <optionValue>
+    cli_app <command> --option <optionValue>
 ```
 - `<command>`: The operation to perform (validate, convert, etc.).
 - `-option <optionValue>`: The option to pass to the command (e.g., file path, output format).
 
 ### GUI
-Use the GUI to explore XML files, format them, and convert to JSON interactively.
+Use the GUI to explore XML files, format them, and convert to JSON interactively as well as analyze the social media XML files using the graph analysis and visualization feature.
