+//! # Kickback Pallet
+//! This pallet implements the [Kickback protocol](https://github.com/wearekickback) for event management via skin-in-the-game incentives.
+//!
+//! ## Overview
+//!
+//! To be admitted to enter an event, an event-specific deposit must be reserved from an account. 
+//! 
+//! ### Terminology
+//! - [`Organizer`] - the account that configures an event.
+//! - [`RsvpList`] - a [`BoundedVec`] of those who have reserved funds, that is limited to [`MaxAttendeeCount`] in size.
+//! - [`AttendanceOracle`] - the [origin](https://docs.substrate.io/build/origins/) that is solely allowed to determine who did and did not attend and event.
+//!

 //! # Kickback Pallet
-//! This pallet implements the [Kickback protocol](https://github.com/wearekickback) for event management via skin-in-the-game incentives.
+//!
+//! This pallet implements the [Kickback protocol](https://github.com/wearekickback) for meeting management via skin-in-the-game incentives.
 //!
 //! ## Overview
 //!
-//! To be admitted to enter an event, an event-specific deposit must be reserved from an account.
+//! To be admitted to an meeting, an per-meeting deposit must be reserved from an account.
 //!
 //! ### Terminology
-//! - [`Organizer`] - the account that configures an event.
-//! - [`RsvpList`] - a [`BoundedVec`] of those who have reserved funds, that is limited to
-//!   [`MaxAttendeeCount`] in size.
-//! - [`AttendanceOracle`] - the [origin](https://docs.substrate.io/build/origins/) that is solely
-//!   allowed to determine who did and did not attend and event.
+//! - [`MeetingDetails`]: Metadata of a specific meeting.
+//! - [`Meetings`]: a [`BoundedVec`] of meeting details that is limited to [`MaxMeetingCount`] in
+//!   size.
+//! - [`DepositorsOf`]: a [`BoundedVec`] of accounts that have deposited for a specific meeting that is
+//!   limited to [`MaxAttendeeCount`] in size.
+//!
+//! ## Considerations
+//!
+//! **Note:** No meeting details are stored on-chain, only the token deposits and incentives are
+//! reasoned about in this pallet.
+//!
+//! All [`MeetingDetails`] include arbitrary meeting details that must be available on an [IPFS](https://ipfs.io) network and have a valid [`Cid`] to access them.
+//! This cannot be mutated once established for a meeting to ensure that all attendees have a common
+//! view of the meeting's information (time, location, requirements other than a deposit to be
+//! admitted, etc.). Most users will want this information to point to a static dApp
+//! that is integrated with this pallet and the network it's hosted on to RSVP for a specific
+//! meeting. This could also simply be linking to a JSON file that could be consumed in a dApp to
+//! interact with this pallet.
