+### Recently used emoji
+
+{{% added-in v="1.18" %}}
+
+This module enables clients to track a user's cumulated emoji usage across different
+devices. The data is stored in the [`m.recent_emoji`](#mrecent_emoji)
+global [account data](#client-config) and can, among other things, be used to
+generate recommendations in emoji pickers.
+
+#### Events
+
+{{% event event="m.recent_emoji" %}}
+
+#### Client behaviour
+
+What exactly constitutes trackable emoji usage is left as an implementation detail
+for clients. It is RECOMMENDED to include sending emoji in both messages and
+annotations.
+
+When an emoji is used, the sending client moves (or adds) it to the beginning of
+the `recent_emoji` array and increments (or initializes) its counter. This keeps
+the array ordered by last usage time which facilitates evaluating the data. How
+exactly the client evaluates and uses the collected data is deliberately left
+unspecified.
+
+To prevent excessive growth of the event as new emoji are being used, clients
+SHOULD limit the length of the `recent_emoji` array by dropping elements from
+its end. A RECOMMENDED maximum length is 100 emoji.
+
+To enable future extension, clients MUST tolerate and preserve array elements
+within `recent_emoji` regardless of whether they understand or support the
+contained `emoji` value. This means ignoring entries with unrecognised values
+of `emoji` when deciding what to display to the user while retaining them when
+modifying the array (unless the modification is for truncation).
+
+To prevent undefined behavior, clients SHOULD remove array elements that
+don't conform to the event schema such as elements with negative counters.
