+## KDE

+I work on various projects that are under the [KDE](https://www.kde.org/) umbrella.
+
+* The Kate editor, a full-featured text editor
+ * https://kate-editor.org/
+ * https://cgit.kde.org/kate.git/
+
+* The KTextEditor framework, a versatile text editor component
+ * https://api.kde.org/frameworks/ktexteditor/html/
+ * https://cgit.kde.org/ktexteditor.git/
+
+* The Syntax-Highlighting framework, close to 300 languages supported
+ * https://api.kde.org/frameworks/syntax-highlighting/html/
+ * https://cgit.kde.org/syntax-highlighting.git/
+
+Contributors to these projects are welcome.
+
+I you wish to sponsor the work done by KDE in non-technical ways, please think about [donating](https://kde.org/donations).
