+//! # Aura Module
+//!
+//! - [`aura::Trait`](./trait.Trait.html)
+//! - [`Module`](./struct.Module.html)
+//!
+//! ## Overview
+//!
+//! The Aura module extends Aura consensus by managing offline reporting.
+//!
+//! ## Interface
+//!
+//! ### Public Functions
+//!
+//! - `slot_duration` - Determine the Aura slot-duration based on the Timestamp module configuration.
+//!
+//! ## Related Modules
+//!
+//! - [Staking](../srml_staking/index.html): The Staking module is called in Aura to enforce slashing
+//!  if validators miss a certain number of slots (see the [`StakingSlasher`](./struct.StakingSlasher.html)
+//!  struct and associated method).
+//! - [Timestamp](../srml_timestamp/index.html): The Timestamp module is used in Aura to track
+//! consensus rounds (via `slots`).
+//! - [Consensus](../srml_consensus/index.html): The Consensus module does not relate directly to Aura,
+//!  but serves to manage offline reporting by implementing `ProvideInherent` in a similar way.
+//!
+//! ## References
+//!
+//! If you're interested in hacking on this module, it is useful to understand the interaction with
+//! `substrate/core/inherents/src/lib.rs` and, specifically, the required implementation of
+//! [`ProvideInherent`](../substrate_inherents/trait.ProvideInherent.html) and
+//! [`ProvideInherentData`](../substrate_inherents/trait.ProvideInherentData.html) to create and check inherents.

-// its type declaration).
-// This works as long as `increase_total_issuance_by` doesn't use the Imbalance

-// This should eventually be refactored so that the three type items that do
-// depend on the Imbalance type (TransactionPayment, TransferPayment, DustRemoval)
-// are placed in their own SRML module.
