Your plugin BufferWithoutOverlaps was created in:
  F:/QGis3_Plugins/Buffers without overlaps/Plugin\buffer_without_overlaps

Your QGIS plugin directory is located at:
  C:/Users/Toni/AppData/Roaming/QGIS/QGIS3/profiles/default/python/plugins

What's Next

1. Test the generated sources using make test (or run tests from your IDE)
2. Copy the entire directory containing your new plugin to the QGIS plugin directory (see Notes below)
3. Test the plugin by enabling it in the QGIS plugin manager and enabling the provider in the Processing Options
4. Customize it by editing the implementation file buffer_without_overlaps_algorithm.py

Notes:

• 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.
• You can also use pb_tool to compile and deploy 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.
