+# single-instance Plugin
+
+This example plugin provides a way to generate hashes of strings.
+
+## Installation
+
+Add the plugin to the `Plugins` option in the Applications options:
+
+```go
+    Plugins: map[string]application.Plugin{
+        "single_instance": single_instance.NewPlugin(&single_instance.Config{
+            // When true, the original app will be activated when a second instance is launched
+            ActivateAppOnSubsequentLaunch: true,
+        }
+    },
+```
+
+## Usage
+
+This plugin prevents the launch of multiple copies of your application. 
+If you set `ActivateAppOnSubsequentLaunch` to true the original app will be activated when a second instance is launched.
+
+## Support
+
+If you find a bug in this plugin, please raise a ticket [here](https://github.com/plugin/repository). 
+Please do not contact the Wails team for support.
+
+## Credit
+
+This plugin contains modified code from the awesome [go-singleinstance](https://github.com/allan-simon/go-singleinstance) module (c) 2015 Allan Simon.
+Original license file has been renamed `go-singleinstance.LICENSE` and is available [here](./singleinstance_LICENSE).
