+#' Get available ICD-10 releases
+#'
+#' @param release A string specifying the release version of ICD-10 to search
+#'   from. If not specified, defaults to the latest release version. See
+#'   the available versions with `icd_versions`.
+#' @param api_version Version of the API. Possible values are `v1` or `v2`.
+#'   For example, if you provide value v2, the API will respond in the format of
+#'   the version 2 of the API. Default is `v2`.
+#' @param language ICD-API is multi-lingual. By changing this header, you may
+#'   make the API respond in different languages. Languages will be available as
+#'   the translations of ICD-11 completes. The values are language codes such as
+#'   en, es, zh, etc. Depending on the `release_id` specified, the available
+#'   languages will vary. Default is English ("en"). Note that language support
+#'   for ICD-10 is limited to English (`en`).
+#' @param category ICD-10 category code or for blocks, the code range.
+#' @param base_url The base URL of the API. Default uses the WHO API server at
+#'   https://id.who.int. If you are using a locally deployed server or hosting
+#'   your own ICD API server, you should specify the URL of your instance here.
+#' @param client The OAuth2 client produced through a call to
+#'   `icd_oauth_client()`.
+#' @param scope Scopes to be requested from the resource owner. Default is
+#'   *"icdapi_access"* as specified in the ICD API documentation.
