+The big advantage of the Download from Overpass API compared to the Download from OSM is that you can limit the download to special objects. For this purpose you can put your Overpass query in the big text box. See [osmwiki:Overpass_API/Overpass_QL] for its syntax. You can add, edit and delete your favorite queries in the list on the right side. Successful executed queries will automatically be added to the list with "history" and the time and date as name of this query. Type text in the small textbox above the list to filter the list.
+
+If `{{geocodeArea}}` is part of the query, it will be evaluated. If `{{bbox}}` is part of the query, then you need to choose the area to download (see below). If none of them is present, then it will search and download global. If the query box is left blank you can download all the data in the below specified area to download.
+
+If you use this download method make sure you know what you are doing as working with incomplete data sets can lead to unwanted wrong or duplicate data after uploading to the osm server. Overpass API offers osm data only (i.e. no gps traces or notes).
+
+The Query Wizard helps you to easily create an Overpass query. See [osmwiki:Overpass_turbo/Wizard] for its syntax and features.

+In the favorite editing window the first box contains the name and the box below the query.

+Additional to the server choose you need to select in which area ("bounding box", "bbox") you want to download the data (except you use an Overpass with `{{bbox}}`). The dialog has multiple tabs.
 
 The Slippy map tab is the most intuitive one as you can simply choose the bbox with your mouse. If you change the bbox in another tab and go back to the Slippy map it will display the new bbox, so you can adjust it before downloading. When the download dialog is called up with data already loaded, the bbox of the downloaded window will be the same like your current [MapView map view].
