+# Scheduler
+A module for scheduling dispatches.
+
+- [`scheduler::Trait`](https://docs.rs/pallet-scheduler/latest/pallet_scheduler/trait.Trait.html)
+- [`Call`](https://docs.rs/pallet-scheduler/latest/pallet_scheduler/enum.Call.html)
+- [`Module`](https://docs.rs/pallet-scheduler/latest/pallet_scheduler/struct.Module.html)
+
+## Overview
+
+This module exposes capabilities for scheduling dispatches to occur at a
+specified block number or at a specified period. These scheduled dispatches
+may be named or anonymous and may be canceled.
+
+**NOTE:** The scheduled calls will be dispatched with the default filter
+for the origin: namely `frame_system::Config::BaseCallFilter` for all origin
+except root which will get no filter. And not the filter contained in origin
+use to call `fn schedule`.
+
+If a call is scheduled using proxy or whatever mecanism which adds filter,
+then those filter will not be used when dispatching the schedule call.
+
+## Interface
+
+### Dispatchable Functions
+
+* `schedule` - schedule a dispatch, which may be periodic, to occur at a
+  specified block and with a specified priority.
+* `cancel` - cancel a scheduled dispatch, specified by block number and
+  index.
+* `schedule_named` - augments the `schedule` interface with an additional
+  `Vec<u8>` parameter that can be used for identification.
+* `cancel_named` - the named complement to the cancel function.
+
+License: Unlicense

+//! # Scheduler
+//! A module for scheduling dispatches.
+//!
+//! - [`Config`]
+//! - [`Call`]
+//! - [`Module`]
+//!
+//! ## Overview
+//!
+//! This module exposes capabilities for scheduling dispatches to occur at a
+//! specified block number or at a specified period. These scheduled dispatches
+//! may be named or anonymous and may be canceled.
+//!
+//! **NOTE:** The scheduled calls will be dispatched with the default filter
+//! for the origin: namely `frame_system::Config::BaseCallFilter` for all origin
+//! except root which will get no filter. And not the filter contained in origin
+//! use to call `fn schedule`.
+//!
+//! If a call is scheduled using proxy or whatever mecanism which adds filter,
+//! then those filter will not be used when dispatching the schedule call.
+//!
+//! ## Interface
+//!
+//! ### Dispatchable Functions
+//!
+//! * `schedule` - schedule a dispatch, which may be periodic, to occur at a
+//!   specified block and with a specified priority.
+//! * `cancel` - cancel a scheduled dispatch, specified by block number and
+//!   index.
+//! * `schedule_named` - augments the `schedule` interface with an additional
+//!   `Vec<u8>` parameter that can be used for identification.
+//! * `cancel_named` - the named complement to the cancel function.
+
+// Ensure we're `no_std` when compiling for Wasm.
