+    \class QWebEngineClientHints
+    \brief The QWebEngineClientHints class provides an object to customize User-Agent Client Hints used by a profile.
+
+    \since 6.8
+
+    \inmodule QtWebEngineCore
+
+    QWebEngineClientHints allows configuration of exposing browser and platform information via
+    User-Agent response and request headers, and a JavaScript API.
+
+    The information accessed via this API is split into two groups: low entropy and high entropy hints.
+    Low entropy hints (\l{QWebEngineClientHints::platform}{platform} and \l{QWebEngineClientHints::mobile}{mobile})
+    are those that do not give away much information; the API makes these accessible with every request and they can not
+    be disabled by QWebEngineClientHints::setAllClientHintsEnabled.
+
+    All the others are high entropy hints; they have the potential to give away more information, therefore they can be
+    disabled by QWebEngineClientHints::setAllClientHintsEnabled.
+
+    Each profile object has its own QWebEngineClientHints object, which configures the
+    Client Hint settings for that browsing context. If a Client Hint is not configured for a web engine
+    profile, its default value is deduced from the system.
