-#' Collection class provides interface for working with Arvados collections.
+#' @description
+#' Collection class provides interface for working with Arvados collections,
+#' for exaplme actions like creating, updating, moving or removing are possible.
#'
-#' @section Usage:
-#' \preformatted{collection = Collection$new(arv, uuid)}
+#' @seealso
+#' \code{\link{https://github.com/arvados/arvados/tree/main/sdk/R}}
#'
-#' @section Arguments:
-#' \describe{
-#' \item{arv}{Arvados object.}
-#' \item{uuid}{UUID of a collection.}
-#' }
-#'
-#' @section Methods:
-#' \describe{
-#' \item{add(content)}{Adds ArvadosFile or Subcollection specified by content to the collection.}
-#' \item{create(files)}{Creates one or more ArvadosFiles and adds them to the collection at specified path.}
-#' \item{remove(fileNames)}{Remove one or more files from the collection.}
-#' \item{move(content, destination)}{Moves ArvadosFile or Subcollection to another location in the collection.}
-#' \item{copy(content, destination)}{Copies ArvadosFile or Subcollection to another location in the collection.}
-#' \item{getFileListing()}{Returns collections file content as character vector.}
-#' \item{get(relativePath)}{If relativePath is valid, returns ArvadosFile or Subcollection specified by relativePath, else returns NULL.}
-#' }
-#'
-#' @name Collection
-#' @examples
