+Scheduling tasks
+================
+
+Pyrogram itself as Telegram MTProto API Framework contains only stuff
+related to Telegram. Scheduling is out of it's scope.
+
+But it is easy to integrate pyrogram with your favourite scheduler.
+
+schedule
+--------
+
+Note that schedule is not suitable for async version of pyrogram.
+
+.. code-block:: python
+
+    import time
+    import schedule
+
+
+    def job():
+        app.send_message("me", "Hi!")
+
+
+    schedule.every(10).minutes.do(job)
+    schedule.every().hour.do(job)
+    schedule.every().day.at("10:30").do(job)
+    schedule.every(5).to(10).minutes.do(job)
+    schedule.every().monday.do(job)
+    schedule.every().wednesday.at("13:15").do(job)
+    schedule.every().minute.at(":17").do(job)
+
+    with app:
+        while True:
+            schedule.run_pending()
+            time.sleep(1)
+
+
+apscheduler
+-----------
+
+.. code-block:: python
+
+    import time
+    from apscheduler.schedulers.background import BackgroundScheduler
+
+
+    def job():
+        app.send_message("me", "Hi!")
+
+
+    scheduler = BackgroundScheduler()
+    scheduler.add_job(job, 'interval', seconds=3)
+
+    scheduler.start()
+    app.run()
+
+Apscheduler supports async version of pyrogram too, here is async example:
+
+.. code-block:: python
+
+    from apscheduler.schedulers.asyncio import AsyncIOScheduler
+
+
+    async def job():
+        await app.send_message("me", "Hi!")
+
+
+    scheduler = AsyncIOScheduler()
+    scheduler.add_job(job, 'interval', seconds=3)
+
+    scheduler.start()
+    app.run()
+

+Scheduling Tasks
 ================
 
-Pyrogram itself as Telegram MTProto API Framework contains only stuff
-related to Telegram. Scheduling is out of it's scope.
+Scheduling tasks means executing one or more functions periodically at pre-defined intervals or after a delay. This is
+useful, for example, to send recurring messages to specific chats or users.
 
-But it is easy to integrate pyrogram with your favourite scheduler.
+Since there's no built-in task scheduler in Pyrogram, this page will only show examples on how to integrate Pyrogram
+with the main Python schedule libraries such as ``schedule`` and ``apscheduler``. For more detailed information, you can
+visit and learn from each library documentation.

Subject: [PATCH 14/14] Update Document file ids to make them compatible again
 with the Bot API Telegram changed something server side on 29 July, 2019
 starting exactly at 04:00 AM UTC+1 (DST), logs say. Looks like Document file
 ids, just like Photo-like ids, are going to change as well after all, if we
 want to keep them compatible with the Bot API
