 =====How can you uninstall your plugin?=====
-(no answer at the moment)
+There are two ways at the moment:
+You can download and run the following script if you want uninstall a plugin or you uninstall and reinstall Droidscript completely. Using the second option causes all your plugins to be uninstalled so you have to reinstall all plugins.
+<code javascript UninstallPlugin.js>
+//Called when application is started.
+function OnStart()
+{
+    //Create a layout with objects vertically centered.
+    lay = app.CreateLayout( "linear", "VCenter,FillXY" );
+    //Create a text label and add it to layout.
+    txt = app.CreateTextEdit( "" );
+    txt.SetHint("Plugin to delete")
+    lay.AddChild( txt );
+    btn=app.CreateButton("Delete Plugin");
+    btn.SetOnTouch(DeleteUserPlugin);
+    lay.AddChild(btn);
+    privFldr = app.GetPrivateFolder( "Plugins" );
+    plgins = app.ListFolder(privFldr);
+    lvw = app.CreateListView( plgins, "Select a Plugin for uninstalling or press Back" );
+    lvw.SetOnTouch( lvw_OnTouch );
+    //Add layout to app.
+    app.AddLayout( lay );
+    lvw.Show();
+}
+function lvw_OnTouch( item )
+{
+  txt.SetText( item );
+}
+function DeleteUserPlugin()
+{
+    var plg = "" + txt.GetText()
+    if (plg == "") return;
