-//! # Module
+//! ## Features
+//!
+//! `spacepackets` supports various runtime environments and is also suitable
+//! for suitable for `no_std` environments. It has several features which may be enabled
+//! for disabled.
+//!
+//! It also offers support for [`serde`](https://serde.rs/). The Space Paccket, PUS TM and TC
+//! implementations derive the `serde` `Serialize` and `Deserialize` trait. This allows serializing and
+//! deserializing them with an appropriate `serde` provider like
+//! [`postcard`](https://github.com/jamesmunns/postcard).
+//!
+//! Default features:
+//!
+//!  - `std`: Enables functionality relying on the standard library.
+//!  - [`alloc`](https://doc.rust-lang.org/alloc/): Enables features which operate on containers
+//!     like [`alloc::vec::Vec`](https://doc.rust-lang.org/beta/alloc/vec/struct.Vec.html).
+//!     Enabled by the `std` features.
+//!
+//! ## Module
 //!
 //! This module contains helpers and data structures to generate Space Packets according to the
 //! [CCSDS 133.0-B-2](https://public.ccsds.org/Pubs/133x0b2e1.pdf). This includes the
 //! [SpHeader] class to generate the Space Packet Header component common to all space packets
 //!
-//! # Example
+//! ## Example
 //!
 //! ```rust
 //! use spacepackets::SpHeader;
