+# Developer Tools
+
+The __Developer__ folder in the __Applications__ folder contains useful development tools for use with helloSystem.
+
+* __PyCharm CE__: A powerful integrated development environment (IDE) for the Python languge which is used for
+many of the utilities and preferences applications in helloSystem
+* __Qt Creator__: The integrated development environment (IDE) for Qt-based applications, such as Menu, Dock, and Filer.
+Includes graphical user interface editors for QtWidgets-based user interfaces (such as Menu and Filer) using `.ui` files 
+and for Qml-based user interfaces (such as Dock) using `.qml` files.
+The user interfaces generated in Qt Creator can be used in Qt application written in C++ or Python
+* __LiteIDE__: An integrated development environment (IDE) for the Go language. Go is recommended
+for long-running processes such as servers and for processes with parallelism
+* __Zeal__: A browser for documentation sets, also known as "docsets". Docsets can be downloaded from within the application
+and are available for many languages and environments, including Python, Qt, and Go.
+
+To minimize the initial download size of the helloSystem image, the applications in the Developer folder
+need to be downloaded prior to first use. You will be guided through this automatic process when you launch these
+applications for the first time. After the applciations have been downloaded, you can use them without an active
+network connection.
