 //! The following features are available. The default features are
 //! `curl-client`, `middleware-logger`, and `encoding`
 //! - __`curl-client` (default):__ use `curl` (through `isahc`) as the HTTP backend.
-//! - __`h1-client`:__ use `async-h1` as the HTTP backend.
+//! - __`h1-client`:__ use `async-h1` as the HTTP backend. For HTTPS, you also need either `native-tls` (to use OpenSSL) or either `rustls`.
 //! - __`hyper-client`:__ use `hyper` (hyper.rs) as the HTTP backend.
 //! - __`wasm-client`:__ use `window.fetch` as the HTTP backend.
+//! - __`native-tls`:__ use OpenSSL for HTTPS (currently only usefull in addition of `h1-client`).
+//! - __`rustls`:__ use rustls for HTTPS (currently only usefull in addition of `h1-client`).
 //! - __`middleware-logger` (default):__ enables logging requests and responses using a middleware.
 //! - __`encoding` (default):__ enables support for body encodings other than utf-8
