+<h2>ECLIPSE THEIA - PROPERTY-VIEW EXTENSION</h2>
+
+<hr />
+
+</div>
+
+## Description
+
+The `@theia/property-view` extension contributes a generic, global property view based on Theia's global selection.
+
+The property view widget can be opened/toggled either via menu _View->Properties_ or via shortcut <kbd>Shift+Alt+P</kbd>. It is located in the bottom dock area by default.
+
+The following two default content widgets are implemented in this extension:
+- EmptyPropertyViewWidget: If no other widget can be provided, a simple message (_No properties available_) is shown.
+- ResourcePropertyViewWidget: Can handle `FileSelection`s and `Navigatable` selections (which provide their resource URI) and displays the general `FileStat` information (e.g. location, name, last modified) in a TreeWidget.
+
+To contribute a specific property view, it is necessary to implement a `PropertyViewDataService` which gathers the property data for a selection as well as a `PropertyViewWidgetProvider` which provides a suitable content widget to display the property data for a specific selection inside the property view widget.
+
+</br>
