Your plugin RoofDraw was created in:
  /home/ana/.local/share/QGIS/QGIS3/profiles/default/python/plugins/roof_draw

Your QGIS plugin directory is located at:
  /home/ana/.local/share/QGIS/QGIS3/profiles/default/python/plugins

What's Next

1. If resources.py is not present in your plugin directory, compile the resources file using pyrcc5 (simply use pb_tool or make if you have automake)
2. Optionally, test the generated sources using make test (or run tests from your IDE)
3. Copy the entire directory containing your new plugin to the QGIS plugin directory (see Notes below)
4. Test the plugin by enabling it in the QGIS plugin manager
5. Customize it by editing the implementation file roof_draw.py
6. Create your own custom icon, replacing the default icon.png
7. Modify your user interface by opening roof_draw_dialog_base.ui in Qt Designer

Notes:

• You can use pb_tool to compile, deploy, and manage your plugin. Tweak the pb_tool.cfg file included with your plugin as you add files. Install pb_tool using pip or easy_install. See http://loc8.cc/pb_tool for more information.
• You can also 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.
