+class InlineQueryHandler(Handler):
+    """The InlineQuery handler class. Used to handle inline queries.
+    It is intended to be used with :meth:`add_handler() <pyrogram.Client.add_handler>`
+
+    For a nicer way to register this handler, have a look at the
+    :meth:`on_inline_query() <pyrogram.Client.on_inline_query>` decorator.
+
+    Args:
+        callback (``callable``):
+            Pass a function that will be called when a new InlineQuery arrives. It takes *(client, inline_query)*
+            as positional arguments (look at the section below for a detailed description).
+
+        filters (:obj:`Filters <pyrogram.Filters>`):
+            Pass one or more filters to allow only a subset of inline queries to be passed
+            in your callback function.
+
+    Other parameters:
+        client (:obj:`Client <pyrogram.Client>`):
+            The Client itself, useful when you want to call other API methods inside the inline query handler.
+
+        inline_query (:obj:`InlineQuery <pyrogram.InlineQuery>`):
+            The received inline query.
