# Fork the project You can use this plugin as your own WFS service extractor. > **Minimal modification:** If you just want an awesome WFS extractor, the only thing you need to do is change the values in `metadata.txt` to fit your service. > **Maximum modification:** If you want to create a complete tool, with logo, documentation and other translation. ## Minimum modification The `metadata.txt` file is located in the `bd_topo_extractor` folder. The values specified in this file concern basic informations on the plugin: - Name - Description - Version - QGIS compatible versions - Author But also some specific informations on the WFS service and the data targeted inside the service : - WFS URL - Schema name - Geometry column name - Crs of the WFS - Methada url - Logo url Modifying those will not change the way the plugin works but all the links and text specific to the BD TOPO®. ## Maximum modification
