+Etherpad is a web-based collaboration platform that allows users to edit text documents together in real time. Multiple users can simultaneously access the same Etherpad document, make changes, and see what others are writing. Etherpad provides a simple and effective way for teamwork, brainstorming, collaborative writing, and more, without version conflicts.
+
+Etherpad is also embedded in Jitsi Meet. This allows for shared notes to be captured during a meeting.
+
+__I've been running Etherpad since the end of 2020: [https://pad.sp-codes.de](https://pad.sp-codes.de)__ Feel free to use Etherpad for your notes as well.

+ntfy is a versatile tool for notification about various events. It also supports UnifiedPush, an open protocol for real-time notifications.
 
-* 
+To use ntfy as a central app for notifications, the app must first be installed on the phone. Then, apps that support UnifiedPush, such as Element, Fluffychat or Tusky can use ntfy as a push provider. This way, not all apps need to keep a connection open to the server and are more energy efficient as a result. In order for you to use my server, you must first set it up in the settings.
+
+__Since May 2023 I provide ntfy for free: [https://ntfy.sp-codes.de](https://ntfy.sp-codes.de)__ You are welcome to use ntfy as push provider for your apps if you like.
