 It allows users to launch text processing tasks, be notified when they finish and see the results.
 The assistant also appears in others apps like Text to easily process parts of a document.
 
+### How to use it
+
+A new right header  menu entry appears. Once clicked, the assistant is displayed and you can select and task type and
+set the input text you want to process.
+
+Once a task is scheduled, it will run as a background job. When it is finished, you will receive a notification
+from which the results can be displayed.
+
+Other apps can integrate with the assistant. For example, Text will display an inline button besides every paragraph
+to directly select a task type to process this paragraph. Selecting a task this way will open the assistant with the task
+being pre-selected and the input text set.
+
+### Text processing providers
+
 In the assistant, the list of available tasks depends on the available providers installed via other apps.
+This means you have complete freedom over which service/software will actually run your text processing tasks.
 So far, the [Large language model](https://github.com/nextcloud/llm#readme)
 and the [OpenAi/LocalAI integration](https://apps.nextcloud.com/apps/integration_openai) apps
