+Plugins
+=======
+
+Pyrogram embeds an **automatic** and lightweight plugin system that is meant to greatly simplify the organization of
+large projects and to provide a way for creating pluggable components that can be **easily shared** across different
+Pyrogram applications with **minimal boilerplate code**.
+
+Introduction
+------------
+
+Prior to the plugin system, pluggable handlers were already possible. For instance, if you wanted to modularize your
+applications, you had to do something like this...
+
+    .. note:: This is an example application that replies in private chats with two messages: one containing the same
+        text message you sent and the other containing the reversed text message (e.g.: "pyrogram" -> "pyrogram" and
+        "margoryp"):
+
+    .. code-block:: text
+
+        myproject/
+            config.ini
+            handlers.py
+            main.py
+
+    - ``handlers.py``
+
+        .. code-block:: python
+
+            def echo(client, message):
+                message.reply(message.text)
+
+
+            def echo_reversed(client, message):
+                message.reply(message.text[::-1])
+
+    - ``main.py``
+
+        .. code-block:: python
+
+            from pyrogram import Client, MessageHandler, Filters
+
+            from handlers import echo, echo_reversed
+
+            app = Client("my_account")
+
+            app.add_handler(
+                MessageHandler(
+                    echo,
+                    Filters.text & Filters.private))
+
+            app.add_handler(
+                MessageHandler(
+                    echo_reversed,
+                    Filters.text & Filters.private),
+                group=1)
+
+            app.run()
+
+...which is already nice and doesn't add *too much* boilerplate code, but things can get boring still; you have to
+manually ``import``, manually :meth:`add_handler <pyrogram.Client.add_handler>` and manually instantiate each
+:obj:`MessageHandler <pyrogram.MessageHandler>` object because **you can't use those cool decorators** for your
+functions. So... What if you could?
+
+Creating Plugins
+----------------
+
+Setting up your Pyrogram project to accommodate plugins is as easy as creating a folder and putting your files full of
+handlers inside.
+
+    .. note:: This is the same example application `as shown above <#introduction>`_, written using the plugin system.
+
+    .. code-block:: text
+        :emphasize-lines: 2, 3
+
+        myproject/
+            plugins/
+                handlers.py
+            config.ini
+            main.py
+
+    - ``plugins/handlers.py``
+
+        .. code-block:: python
+            :emphasize-lines: 4, 9
+
+            from pyrogram import Client, Filters
+
+
+            @Client.on_message(Filters.text & Filters.private)
+            def echo(client, message):
+                message.reply(message.text)
+
+
+            @Client.on_message(Filters.text & Filters.private, group=1)
+            def echo_reversed(client, message):
+                message.reply(message.text[::-1])
+
+    - ``main.py``
+
+        .. code-block:: python
+
+            from pyrogram import Client
+
+            Client("my_account").run()
+
+The first important thing to note is the ``plugins`` folder, whose name is default and can be changed easily by setting
+the ``plugins_dir`` parameter when creating a :obj:`Client <pyrogram.Client>`; you can put any python file in the
+plugins folder and each file can contain any decorated function (handlers). Your Pyrogram Client instance (in the
+``main.py`` file) will **automatically** scan the folder upon creation to search for valid handlers and register them
+for you.
+
+Then you'll notice you can now use decorators. That's right, you can apply the usual decorators to your callback
+functions in a static way, i.e. **without having the Client instance around**: simply use ``@Client`` (Client class)
+instead of the usual ``@app`` (Client instance) namespace and things will work just the same.
+
+The ``main.py`` script is now at its bare minimum and cleanest state.
