 #' @description
 #' Access to GPT-3's functions requires an API key that you obtain from [https://openai.com/api/](https://openai.com/api/). `gpt3.authenticate()` accepts your API key and ensures that you can connect to the models. `gpt3.endsession()` overwrites your API key _for this session_ (it is recommended that you run this when you are done). `check_apikey_form()` is a simple check if any information has been provided at all.
-#' @param apikey A character vector that is your personal API key
+#' @param path The file path to the API key
 #' @return A confirmation message
+#' @details The easiest way to store you API key is in a `.txt` file with _only_ the API key in it (without quotation marks or other common string indicators). `gpt3.authenticate()` reads the single file you point it to and retrieves the content as authentication key for all requests.
