+`api_key` is the only required parameter.
+
+Without `api_secret`, auth commands will not work. This includes usage of session key in place of username for typically non-auth functions.
+
 For user agent, please initialize this with an easily identifiable name (preferably one that would lead to your program if googled). You can choose to not set one, in which case `lastfm-typed-npm` will be set as the user agent. This is probably the best idea if your program is not public.
 
+`secureConnection` determines whether to use https or http. By default, this is `false`, which uses http. Set to `true` to use https. Note that this will most likely be defaulted to true in a future major update.

 Then we can call methods as needed.
