 As you can see, `downloadHandler` takes a `filename` argument, which tells the web browser what filename to default to when saving. This argument can either be a simple string, or it can be a function that returns a string (as is the case here).
 
-The `content` argument must be a function that takes a single argument, a binary write-only connection. The `content` function is responsible for writing the contents of the file download into the connection object.
+The `content` argument must be a function that takes a single argument, the file name of a non-existent temp file. The `content` function is responsible for writing the contents of the file download into that temp file.
 
 Both the `filename` and `content` arguments can use reactive values and functions (although in the case of `filename`, be sure your argument is an actual function; `filename = paste(input$dataset, '.csv')` is not going to work the way you want it to, since it is evaluated only once, when the download handler is being defined).
