+This is a non-core example module for [ProseMirror](https://prosemirror.net).
+ProseMirror is a well-behaved rich semantic content editor based on
+contentEditable, with support for collaborative editing and custom
+document schemas.
+
+This module implements a plugin that shows a drop cursor for
+ProseMirror.
+
+The [project page](https://prosemirror.net) has more information, a
+number of [examples](https://prosemirror.net/examples/) and the
+[documentation](https://prosemirror.net/docs/).

+## Documentation
+
+* **`dropCursor`**`(options?: interface = {}) → Plugin`\
+   Create a plugin that, when added to a ProseMirror instance,
+   causes a decoration to show up at the drop position when something
+   is dragged over the editor.
+
+   Nodes may add a `disableDropCursor` property to their spec to
+   control the showing of a drop cursor inside them. This may be a
+   boolean or a function, which will be called with a view, a
+   position, and the DragEvent, and should return a boolean.
+
+    * **`options`**
+
+       * **`color`**`?: string`\
+         The color of the cursor. Defaults to `black`.
+
+       * **`width`**`?: number`\
+         The precise width of the cursor in pixels. Defaults to 1.
+
+       * **`class`**`?: string`\
+         A CSS class name to add to the cursor element.
