+# Edit & delete tools
+
+## Editing
+
+On the detail page of a tool you will find the **Edit** button
+(only for the person who created the tool, as well as for admins).
+
+The edit page (`/tools/:id/edit`) contains the same fields as when
+creating (name, category, website/icon URL, description, features, tags) —
+already filled with the current values.
+
+- **Save** applies the changes.
+- **Cancel** takes you back to the detail page.
+
+API reference: [`PATCH /tools/{id}`](/docs/reference/endpoints/tools#updateTool).
+
+## Deleting
+
+Via **Delete** on the detail page the tool is removed. The behavior
+depends on your plan:
+
+- **With trash access** (Premium/Enterprise or Admin): the tool is
+  **soft deleted** — it disappears from all public views, but can
+  be restored or permanently deleted in the [trash](/docs/handbook/papierkorb).
+- **Without trash access:** the tool is **permanently** deleted and cannot
+  be restored.
+
+Deletion is only possible for the person who created the tool, as well as
+for admins.
+
+API reference: [`DELETE /tools/{id}`](/docs/reference/endpoints/tools#deleteTool).
