-        As of ODK Central v1.2, you can use `%24expand=*` to expand all repeat repetitions. This is helpful if you'd rather get one nested JSON data payload of all hierarchical data, rather than retrieve each of repeat as a separate flat table with references.
+        As of ODK Central v1.2, you can use `$expand=*` to expand all repeat repetitions. This is helpful if you'd rather get one nested JSON data payload of all hierarchical data, rather than retrieve each of repeat as a separate flat table with references.
 
         The _nonstandard_ `$wkt` querystring parameter may be set to `true` to request that geospatial data is returned as a [Well-Known Text (WKT) string](https://en.wikipedia.org/wiki/Well-known_text) rather than a GeoJSON structure. This exists primarily to support Tableau, which cannot yet read GeoJSON, but you may find it useful as well depending on your mapping software. **Please note** that both GeoJSON and WKT follow a `(lon, lat, alt)` coördinate ordering rather than the ODK-proprietary `lat lon alt`. This is so that the values map neatly to `(x, y, z)`. GPS accuracy information is not a part of either standards specification, and so is presently omitted from OData output entirely. GeoJSON support may come in a future version.
