+# Sponsoring
+
+![Sponsoring flow](./sponsoring-flow.drawio.svg)
+
+## Implementation
+
+If you need to add sponsoring for pallet call, you should implement `SponsorshipHandler<AccountId, Call, ()>`, see `UniqueSponsorshipHandler` for example.
+
+If you need to add sponsoring for EVM contract call, you should implement `SponsorshipHandler<CrossAccountId, (H160, Vec<u8>), CallContext>`, see `UniqueEthSponsorshipHandler` for example.
+
+## EVM bridging
+
+In case if Ethereum call is being called using substrate `evm.call` extrinsic, `BridgeSponsorshipHandler` is used to convert between two different `SponsorshipHandler` types

+//!

-//! The app promotion pallet is designed to ... .
+//! - [`Config`]
+//! - [`Pallet`]
+//! - [`Error`]
+//! - [`Event`]
+//!
+//! ## Overview
+//! The App Promotion pallet allows fund holders to stake at a certain daily rate of return.
+//! The mechanics implemented in the pallet allow it to act as a sponsor for collections / contracts,
+//! the list of which is set by the pallet administrator.

 //!
 //! ## Interface
+//!	The pallet provides interfaces for funds, collection/contract operations (see [types] module).

 //!
 //! ### Dispatchable Functions
+//!	- [`set_admin_address`][`Pallet::set_admin_address`] - sets an address as the the admin.
+//! - [`stake`][`Pallet::stake`] - stakes the amount of native tokens.
+//! - [`unstake`][`Pallet::unstake`] - unstakes all stakes.
+//! - [`sponsor_collection`][`Pallet::sponsor_collection`] - sets the pallet to be the sponsor for the collection.
+//! - [`stop_sponsoring_collection`][`Pallet::stop_sponsoring_collection`] - removes the pallet as the sponsor for the collection.
+//! - [`sponsor_contract`][`Pallet::sponsor_contract`] - sets the pallet to be the sponsor for the contract.
+//! - [`stop_sponsoring_contract`][`Pallet::stop_sponsoring_contract`] - removes the pallet as the sponsor for the contract.
+//! - [`payout_stakers`][`Pallet::payout_stakers`] - recalculates interest for the specified number of stakers.
