-To use the observational datasets, `rdwd` has been designed to mainly do 3 things:
-
-* `r helplink("selectDWD")`: facilitate file selection, needing:
-  * station id/name/location (see chapter [station selection](station-selection.html))
-  * temporal resolution (**res** = 1/10 minutes, hourly, daily, monthly, annual)

-* `r helplink("dataDWD")`: download a file (or multiple files), without re-downloads for existing files
-
-* `r helplink("readDWD")`: read that data into R (including useful defaults for metadata)
-
-`r helplink("selectDWD")` uses the result from `r helplink("indexFTP")` which recursively lists all the files on an FTP-server (using `RCurl::getURL`).
-As this is time consuming, the result is stored in the package dataset `r helplink("fileIndex")`.
-From this, `r helplink("metaIndex")` and `r helplink("geoIndex")` are derived.
