 //! # No-std support
 //!
-//! This crate currently requires the Rust standard library. For JSON support in
-//! Serde without a standard library, please see the [`serde-json-core`] crate.
+//! As long as there is a memory allocator, it is possible to use serde_json
+//! without the rest of the Rust standard library. This is supported on Rust
+//! 1.36+. Disable the default "std" feature and enable the "alloc" feature:
+//!
+//! ```toml
+//! [dependencies]
+//! serde_json = { version = "1.0", default-features = false, features = ["alloc"] }
+//! ```
+//!
+//! For JSON support in Serde without a memory allocator, please see the
+//! [`serde-json-core`] crate.
