-# Vesting Module
-
-## Overview
-
-Vesting module provides a means of scheduled balance lock on an account. It uses the *graded vesting* way, which unlocks a specific amount of balance every period of time, until all balance unlocked.
-
-### Vesting Schedule
-
-The schedule of a vesting is described by data structure `VestingSchedule`: from the block number of `start`, for every `period` amount of blocks, `per_period` amount of balance would unlocked, until number of periods `period_count` reached. Note in vesting schedules, *time* is measured by block number. All `VestingSchedule`s under an account could be queried in chain state.

-//! # Vesting Module
-//!
-//! ## Overview
-//!
-//! Vesting module provides a means of scheduled balance lock on an account. It
-//! uses the *graded vesting* way, which unlocks a specific amount of balance
-//! every period of time, until all balance unlocked.
-//!
-//! ### Vesting Schedule
-//!
-//! The schedule of a vesting is described by data structure `VestingSchedule`:
-//! from the block number of `start`, for every `period` amount of blocks,
-//! `per_period` amount of balance would unlocked, until number of periods
-//! `period_count` reached. Note in vesting schedules, *time* is measured by
-//! block number. All `VestingSchedule`s under an account could be queried in
-//! chain state.
-//!
-//! ## Interface
-//!
-//! ### Dispatchable Functions
-//!
-//! - `vested_transfer` - Add a new vesting schedule for an account.
-//! - `claim` - Claim unlocked balances.
-//! - `update_vesting_schedules` - Update all vesting schedules under an
-//!   account, `root` origin required.
