 # Markdown Extension
 
-I'm trying to create markdown new tab extension with [Milkdown](https://milkdown.dev/) and
+Markdown Editor for new tab made with [Milkdown](https://milkdown.dev/) and
 [Dockview](https://dockview.dev).
 
-Now its only experiment, but it already handles grid layout and data persistance.
