Your plugin TestPlugin was created in:
  /Users/gsherman/development/qgis_plugins/TestPlugin

Your QGIS plugin directory is located at:
  /Users/gsherman/.qgis2/python/plugins

What's Next

1. Copy the entire directory containing your new plugin to the QGIS plugin directory
2. Compile the resources file using rcc (simply run make if you have automake)
3. Test the generated sources using make test (or run tests from your IDE)
4. Test the plugin by enabling it in the QGIS plugin manager
5. Customize it by editing the implementation file test_plugin.py
6. Create your own custom icon, replacing the default icon.png
7. Modify your user interface by opening test_plugin_dialog_base.ui in Qt Designer
8. You can use the Makefile to compile and deploy when you make changes. This requires GNU make (gmake). The Makefile is ready to use, however you will have to edit it to add addional Python source files, dialogs, and translations.
