+The Linux implementation of [`url_launcher`][1].
+
+## Usage
+
+### Import the package
+
+This package is an unendorsed Linux implementation of `url_launcher`.
+
+In order to use this now, you'll need to depend on `url_launcher_linux`.
+When this package is endorsed it will be automatically used by the `url_launcher` package and you can switch to that API.
