-Detailed information about the Portfolio Performance program could be found in the menu `Help > About Portfolio Performance`. The top panel contains the version, e.g. 0.67.0 from december 2023, the platform and the Java version it runs on. The platform could be Windows (win32, x86_64), Linux, or macOS; see [Installation](../../getting-started/installation.md). The Portfolio Performance program is built with the Java programming language. The most recent Long Term Support (LTS) version of the OpenJDK (Java Development Kit) is obtained through [Azul.com](https://www.azul.com/downloads/?package=jdk#zulu). From the copyright info, you learn that the author `Andreas Buchen` started development back in 2012.

-## Software
+## About Panel Overview
 
-[Eclipse Foundation](https://www.eclipse.org/): Eclipse is a free and open source software development environment that supports various languages, platforms and plugins. It is a very popular and widely used IDE (Integrated Development Environment). Eclipse allows developers to create, test, debug, and deploy applications using a common framework and a rich set of tools. From a user perspective, the choice of a specific IDE is not important. The development platform e.g. Java SDK however is very much.

-[Apache Software Foundation](https://apache.org/): Several libraries are used; for example to extract text and metadata from PDF documents, and to perform HTTP requests and handle responses (e.g. communicate with Portfolio Report). 
+![About Portfolio Performance Panel](./images/about.png)
 
-[SWT Chart Project](https://github.com/eclipse/swtchart/wiki): The Eclipse SWTChart software is used to create the line and pie charts in the app. Portfolio Performance uses the Standard Widget Toolkit (SWT) which is a graphical user interface (GUI) library that allows Java developers to create native-looking applications for different platforms. You enable this library in `Help > Preferences > General`.
+---
 
-[Tree Map Library](https://github.com/smurf667/treemaplib): Treemaps represent a distinct visualization technique for illustrating hierarchical data by using a series of nested rectangles. This kind of map is used in the Taxonomies menu.
+### Top Section
 
-[jsoup Java HTML Parser](https://jsoup.org/): jsoup is a Java library that simplifies working with real-world HTML and XML. It offers an easy-to-use API for URL fetching, data parsing, extraction, and manipulation using DOM API methods, CSS, and xpath selectors. The library is used for example to fetch the historical prices from a table on a financial website.
+- **Version:** 0.76.2 (May 2025)
+- **Platform:** Windows (win32, x86*64), Linux, or macOS  
+  See [Installation](../../getting-started/installation.md) for details.
+- **Java Version:** Version of the Java Runtime Environment (JRE) or Java Development Kit (JDK) used  
+  Portfolio Performance is developed in **Java**. It is recommended to use the latest **Long-Term Support (LTS)** OpenJDK version, available from [Azul Zulu](https://www.azul.com/downloads/?package=jdk#zulu).
+- The project was started in 2012 by **Andreas Buchen**.
 
-[JSON.simple](https://github.com/fangyidong/json-simple): JSON.simple is a simple Java toolkit for JSON. You can use JSON.simple to encode or decode JSON text. This tool is used in the app for downloading historical prices from a JSON data source.
+---
 
-[Protobuf](https://github.com/protocolbuffers/protobuf): Protocol Buffers (a.k.a., protobuf) are Google's language-neutral, platform-neutral, extensible mechanism for serializing structured data. The software is used to convert the XML-datastructures of the portfolio file into Java usable data structures.  
+### Bottom Section
 
-[Guava](https://github.com/google/guava): The Guava libraries are intended to complement the core java libraries and make working in the Java language more pleasant and more productive.

+  Detailed information about the environment Portfolio Performance runs in (operating system, Java and Eclipse components, log file paths, etc.)
 
-[JsonPath](https://github.com/json-path/JsonPath): JsonPath is a query language for JSON. It allows to select and extract a sub-section from a JSON document using a simple syntax that is similar to XPath for XML.
+---
 
-[D3.js](https://d3js.org/): D3.js is an abbreviation for Data-Driven Documents and is a JavaScript library to work on data visualization e.g. graphs. 
+## Key Software Components & Libraries
 
-[XStream](https://github.com/x-stream/xstream): A Java library that allows you to serialize and deserialize Java objects to and from XML or JSON.
+Portfolio Performance leverages a robust set of open-source libraries and frameworks to deliver its features, ensure cross-platform compatibility, and provide a native user experience:
 
-[OpenJDK](https://openjdk.org/): Running a Java program on for example a Windows machine requires that the Java Development Kit (JDK) is installed on that computer. Portfolio Performance uses the JDK provided by Azul.com.
+- **[Eclipse Foundation](https://www.eclipse.org/)**  
+  The backbone development platform for Portfolio Performance. Eclipse provides the **Integrated Development Environment (IDE)** and the **Standard Widget Toolkit (SWT)**, a GUI toolkit used to create native-looking graphical interfaces across platforms. SWT enables rendering components that feel consistent on Windows, Linux, and macOS by using the underlying OS widgets.
 
-## Code Contributors
