//! # Collectives Parachain
//!
//! This parachain is for collectives that serve the Polkadot network.
//! Each collective is defined by a specialized (possibly instanced) pallet.
//!
//! ### Governance
//!
//! As a common good parachain, Collectives defers its governance (namely, its `Root` origin), to its
//! Relay Chain parent, Polkadot.
//!
//! ### Collator Selection
//!
//! Collectives uses `pallet-collator-selection`, a simple first-come-first-served registration
//! system where collators can reserve a small bond to join the block producer set. There is no
//! slashing. Collective members are generally expected to run collators.
//!
