 ### Usage
 If you want to render with Vivify with the flags `-r`, `--render` or with the option in the config file, you must have installed the plugins for your specific editor ([for Vim and Neovim](https://github.com/jannis-baum/vivify.vim))
 
+
+### Editor support
+
+`NoteWrapper` relies on certain editor features, so not all of its functionality is supported by every editor.
+
+Here are the features that depend on editor support:
+
+- **Bufferless rendering**: As soon as you write something in the note (even without saving), it is rendered.
+- **Cursor following**: The rendered view follows your cursor. For example, if you move to the bottom of a note, the rendered view will also scroll to the bottom.
+- **Jump to end on open**: Automatically jumps to the end of the file when opening it.
+
+The first two features depend on [Vivify's plugin for editors](https://github.com/jannis-baum/Vivify?tab=readme-ov-file#existing-integration).
+
+| Editor  | Bufferless | Cursor | Jump to end |
+|---------|------------|--------|-------------|
+| Neovim  | ✅         | ✅     | ✅          |
+| Vim     | ✅         | ✅     | ✅          |
+| Nano    | ❌         | ❌     | ✅          |
