+# Smile Autopaste
+
+A Cinnamon extension that automatically pastes emojis selected in [Smile](https://github.com/mijorus/smile) into the previously focused window.
+
+![Screenshot of the Smile Autopaste plugin](./screenshot.png)
+
+## How it works
+
+When you pick an emoji in Smile, Smile copies it to the clipboard and emits a D-Bus signal. This extension listens for that signal and replays `Ctrl+V` into the previously focused window after a short delay, so the emoji lands where the user's cursor was.
+
+## Requirements
+
+- [Smile](https://github.com/mijorus/smile) emoji picker must be installed and running.
+
+## Installation
+
+Clone this repository and copy `files/smile-autopaste@turtl.cc` into `~/.local/share/cinnamon/extensions/`.
