+//!
+//! ## `Cell<T>`
+//!
+//! [`Cell<T>`] implements interior mutability by moving values in and out of the cell. That is, an
+//! `&mut T` to the inner value can never be obtained, and the value itself cannot be directly
+//! obtained without replacing it with something else. Both of these rules ensure that there is
+//! never more than one reference pointing to the inner value. This type provides the following
+//! methods:

 //!  - For types that implement [`Copy`], the [`get`](Cell::get) method retrieves the current

+//!    interior value by duplicating it.
 //!  - For types that implement [`Default`], the [`take`](Cell::take) method replaces the current
 //!    interior value with [`Default::default()`] and returns the replaced value.
-//!  - For all types, the [`replace`](Cell::replace) method replaces the current interior value and
-//!    returns the replaced value and the [`into_inner`](Cell::into_inner) method consumes the
-//!    `Cell<T>` and returns the interior value. Additionally, the [`set`](Cell::set) method
-//!    replaces the interior value, dropping the replaced value.
+//!  - All types have:
+//!    - [`replace`](Cell::replace): replaces the current interior value and returns the replaced
+//!      value.
+//!    - [`into_inner`](Cell::into_inner): this method consumes the `Cell<T>` and returns the
+//!      interior value.
+//!    - [`set`](Cell::set): this method replaces the interior value, dropping the replaced value.
+//!
+//! `Cell<T>` is typically used for more simple types where copying or moving values isn't too
+//! resource intensive (e.g. numbers), and should usually be preferred over other cell types when
+//! possible. For larger and non-copy types, `RefCell` provides some advantages.
+//!

+//! [`RefCell<T>`] uses Rust's lifetimes to implement "dynamic borrowing", a process whereby one can
 //! claim temporary, exclusive, mutable access to the inner value. Borrows for `RefCell<T>`s are
-//! tracked 'at runtime', unlike Rust's native reference types which are entirely tracked
-//! statically, at compile time. Because `RefCell<T>` borrows are dynamic it is possible to attempt
-//! to borrow a value that is already mutably borrowed; when this happens it results in thread
-//! panic.
+//! tracked at _runtime_, unlike Rust's native reference types which are entirely tracked
+//! statically, at compile time.
+//!
+//! An immutable reference to a `RefCell`'s inner value (`&T`) can be obtained with
+//! [`borrow`](`RefCell::borrow`), and a mutable borrow (`&mut T`) can be obtained with
+//! [`borrow_mut`](`RefCell::borrow_mut`). When these functions are called, they first verify that
+//! Rust's borrow rules will be satisfied: any number of immutable borrows are allowed or a
+//! single immutable borrow is allowed, but never both. If a borrow is attempted that would violate
+//! these rules, the thread will panic.
+//!
+//! The corresponding [`Sync`] version of `RefCell<T>` is [`RwLock<T>`].
+//!
+//! ## `OnceCell<T>`
+//!
+//! [`OnceCell<T>`] is somewhat of a hybrid of `Cell` and `RefCell` that works for values that
+//! typically only need to be set once. This means that a reference `&T` can be obtained without
+//! moving or copying the inner value (unlike `Cell`) but also without runtime checks (unlike
+//! `RefCell`). However, its value can also not be updated once set unless you have a mutable
+//! reference to the `OnceCell`.
+//!
+//! `OnceCell` provides the following methods:
+//!
+//! - [`get`](OnceCell::get): obtain a reference to the inner value
+//! - [`set`](OnceCell::set): set the inner value if it is unset (returns a `Result`)
+//! - [`get_or_init`](OnceCell::get_or_init): return the inner value, initializing it if needed
+//! - [`get_mut`](OnceCell::get_mut): provide a mutable reference to the inner value, only available
+//!   if you have a mutable reference to the cell itself.
+//!
+//! The corresponding [`Sync`] version of `OnceCell<T>` is [`OnceLock<T>`].
