+
+//! flat_set is a Sorted Associative Container that stores objects of type Key.
+//! It is also a Unique Associative Container, meaning that no two elements are the same.
+//!
+//! flat_set is similar to std::set but it's implemented by as an ordered sequence container.
+//! The underlying sequence container is by default <i>vector</i> but it can also work
+//! user-provided vector-like SequenceContainers (like <i>static_vector</i> or <i>small_vector</i>).
+//!
+//! Using vector-like sequence containers means that inserting a new element into a flat_set might invalidate
+//! previous iterators and references (unless that sequence container is <i>stable_vector</i> or a similar
+//! container that offers stable pointers and references). Similarly, erasing an element might invalidate
+//! iterators and references pointing to elements that come after (their keys are bigger) the erased element.
+//!
+//! This container provides random-access iterators.
+//!
+//! \tparam Key is the type to be inserted in the set, which is also the key_type
+//! \tparam Compare is the comparison functor used to order keys
+//! \tparam AllocatorOrContainer is either:
+//! - The allocator to allocate <code>value_type</code>s (e.g. <i>allocator< std::pair<Key, T> > </i>).
+//! (in this case <i>sequence_type</i> will be vector<value_type, AllocatorOrContainer>)
+//! - The SequenceContainer to be used as the underlying <i>sequence_type</i>. It must be a vector-like
+//! sequence container with random-access iterators.
