-//! # MMR Digest Pallet
+//! # Chain MMR Pallet
+//!
+//! \## Overview
+//! This is the pallet to maintain accumulate headers Merkle Mountain Range
+//! and push the mmr root in to the digest of block headers on finalize.
+//! MMR can be used for light client to implement super light clients,
+//! and can also be used in other chains to implement chain relay for
+//! cross-chain verification purpose.
+//!
+//! \## Terminology
+//!
+//! \### Merkle Moutain Range
+//! For more details about the MMR struct, refer https://github.com/mimblewimble/grin/blob/master/doc/mmr.md#structure
+//!
+//! \### MMR Proof
+//! Using the MMR Store Storage, MMR Proof can be generated for specific
+//! block header hash. Proofs can be used to verify block inclusion together with
+//! the mmr root in the header digest.
+//!
+//! \### Positions
+//! The index position of the nodes(and hash leave nodes) in the mmr node list
+//! constructed using MMR struct
+//!
+//! \### Digest Item
+//! The is a ```MerkleMountainRangeRoot(Hash)``` digest item pre-subscribed in Digest.
+//! This is implemented in Darwinia's fork of substrate: https://github.com/darwinia-network/substrate
+//! The Pull request link is https://github.com/darwinia-network/substrate/pull/1
+//!
+//! \## Implementation
+//! We are using the MMR library from https://github.com/nervosnetwork/merkle-mountain-range
+//! Pull request: https://github.com/darwinia-network/darwinia/pull/358
+//!
+//! \## References
+//! Darwinia Relay's Technical Paper:
+//! https://github.com/darwinia-network/rfcs/blob/master/paper/Darwinia_Relay_Sublinear_Optimistic_Relay_for_Interoperable_Blockchains_v0.7.pdf

 //! # Chain MMR Pallet
 //!
-//! \## Overview
+//! ## Overview
 //! This is the pallet to maintain accumulate headers Merkle Mountain Range
 //! and push the mmr root in to the digest of block headers on finalize.
 //! MMR can be used for light client to implement super light clients,
 //! and can also be used in other chains to implement chain relay for
 //! cross-chain verification purpose.
 //!
-//! \## Terminology
+//! ## Terminology

-//! \### Merkle Moutain Range
+//! ### Merkle Moutain Range
 //! For more details about the MMR struct, refer https://github.com/mimblewimble/grin/blob/master/doc/mmr.md#structure
 //!
-//! \### MMR Proof
+//! ### MMR Proof
 //! Using the MMR Store Storage, MMR Proof can be generated for specific
 //! block header hash. Proofs can be used to verify block inclusion together with
 //! the mmr root in the header digest.
 //!
-//! \### Positions
+//! ### Positions
 //! The index position of the nodes(and hash leave nodes) in the mmr node list
 //! constructed using MMR struct
 //!
-//! \### Digest Item
+//! ### Digest Item
 //! The is a ```MerkleMountainRangeRoot(Hash)``` digest item pre-subscribed in Digest.
 //! This is implemented in Darwinia's fork of substrate: https://github.com/darwinia-network/substrate
 //! The Pull request link is https://github.com/darwinia-network/substrate/pull/1
