+# Example: `ghostty-vt` Zig Module
+
+This contains a simple example of how to use the `ghostty-vt` Zig module
+exported by Ghostty to have access to a production grade terminal emulator.
+
+Requires the Zig version stated in the `build.zig.zon` file.
+
+## Usage
+
+Run the program:
+
+```shell-session
+zig build run
+```
