 \description{
 Access to GPT-3's functions requires an API key that you obtain from \url{https://openai.com/api/}. \code{gpt3.authenticate()} accepts your API key and ensures that you can connect to the models. \code{gpt3.endsession()} overwrites your API key \emph{for this session} (it is recommended that you run this when you are done). \code{check_apikey_form()} is a simple check if any information has been provided at all.
 }
+\details{
+The easiest way to store you API key is in a \code{.txt} file with \emph{only} the API key in it (without quotation marks or other common string indicators). \code{gpt3.authenticate()} reads the single file you point it to and retrieves the content as authentication key for all requests.

 # Starting a session:
 gpt3.authenticate(apikey = 'REPLACE_THIS_WITH_YOUR_KEY')
