 We use `GitHub Discussions <https://github.com/hathach/tinyusb/discussions>`_ as our forum. It is a great place to ask questions and advice from the community or to discuss your TinyUSB-based projects.
 
 For bugs and feature requests, please `raise an issue <https://github.com/hathach/tinyusb/issues>`_ and follow the templates there.

 SETUP packets are a special type of transaction that can occur at any time on the control endpoint, numbered ``0``. Since they are unique, most peripherals have special handling for them. Their data is always 8 bytes in length as well.
 
 Calls to this look like:
 
-.. code-block::
+.. code-block:: c
 
    dcd_event_setup_received(0, setup, true);
 
 
-As before with ``dcd_event_bus_signal`` the first argument is the USB peripheral number and the third is true to signal its being called from an interrupt handler. The middle argument is byte array of length 8 with the contents of the SETUP packet. It can be stack allocated because it is copied into the queue.

 Endpoints
 ~~~~~~~~~
 
 Endpoints are the core of the USB data transfer process. They come in a few forms such as control, isochronous, bulk, and interrupt. We won't cover the details here except with some caveats in open below. In general, data is transferred by setting up a buffer of a given length to be transferred on a given endpoint address and then waiting for an interrupt to signal that the transfer is finished. Further details below.
 
-Endpoints within USB have an address which encodes both the number and direction of an endpoint. TinyUSB provides ``tu_edpt_number`` and ``tu_edpt_dir`` to unpack this data from the address. Here is a snippet that does it.

 Opening an endpoint is done for all non-control endpoints once the host picks a configuration that the device should use.

+At this point you should have everything working! 🙂 Of course, you may not write perfect code. Here are some tips and tricks for debugging.
 
 Use `WireShark <https://www.wireshark.org/>`_ or `a Beagle <https://www.totalphase.com/protocols/usb/>`_ to sniff the USB traffic. When things aren't working its likely very early in the USB enumeration process. Figuring out where can help clue in where the issue is. For example:
 
 
 * If the host sends a SETUP packet and its not ACKed then your USB peripheral probably isn't started correctly.
-* If the peripheral is started correctly but it still didn't work, then verify your usb clock is correct. (You did output a PWM based on it right? ;-) )
+* If the peripheral is started correctly but it still didn't work, then verify your usb clock is correct. (You did output a PWM based on it right? 🙂)

(Also, if you are using your own code instead of an example ``tud_task`` may not be called.) If that's OK, the ``dcd_xfer_complete`` may not be setting up the next transaction correctly.

+Supported Boards
+****************
+
+The board support code is only used for self-contained examples and testing. It is not used when TinyUSB is part of a larger project.
+It is responsible for getting the MCU started and the USB peripheral clocked with minimal of on-board devices
+
+-  One LED : for status
+-  One Button : to get input from user
+-  One UART : optional for device, but required for host examples
+
+Following boards are supported

-Device Stack
-============
-
-Supports multiple device configurations by dynamically changing USB descriptors, low power functions such like suspend, resume, and remote wakeup. The following device classes are supported:
-
--  Audio Class 2.0 (UAC2)
--  Bluetooth Host Controller Interface (BTH HCI)
--  Communication Device Class (CDC)
--  Device Firmware Update (DFU): DFU mode (WIP) and Runtime
--  Human Interface Device (HID): Generic (In & Out), Keyboard, Mouse, Gamepad etc ...
--  Mass Storage Class (MSC): with multiple LUNs
--  Musical Instrument Digital Interface (MIDI)
--  Network with RNDIS, Ethernet Control Model (ECM), Network Control Model (NCM)
--  Test and Measurement Class (USBTMC)
--  Video class 1.5 (UVC): work in progress
--  Vendor-specific class support with generic In & Out endpoints. Can be used with MS OS 2.0 compatible descriptor to load winUSB driver without INF file.
--  `WebUSB <https://github.com/WICG/webusb>`__ with vendor-specific class
-
-If you have a special requirement, `usbd_app_driver_get_cb()` can be used to write your own class driver without modifying the stack. Here is how the RPi team added their reset interface `raspberrypi/pico-sdk#197 <https://github.com/raspberrypi/pico-sdk/pull/197>`_
-
-Host Stack
-==========
-
-- Human Interface Device (HID): Keyboard, Mouse, Generic
-- Mass Storage Class (MSC)
-- Communication Device Class: CDC-ACM
-- Vendor serial over USB: FTDI, CP210x
-- Hub with multiple-level support
-
-Similar to the Device Stack, if you have a special requirement, `usbh_app_driver_get_cb()` can be used to write your own class driver without modifying the stack.
-
-TypeC PD Stack
-==============
-
-- Power Delivery 3.0 (PD3.0) with USB Type-C support (WIP)
-- Super early stage, only for testing purpose
-- Only support STM32 G4
-
-OS Abstraction layer
-====================
-
-TinyUSB is completely thread-safe by pushing all Interrupt Service Request (ISR) events into a central queue, then processing them later in the non-ISR context task function. It also uses semaphore/mutex to access shared resources such as Communication Device Class (CDC) FIFO. Therefore the stack needs to use some of the OS's basic APIs. Following OSes are already supported out of the box.
-
-- **No OS**
-- **FreeRTOS**
-- `RT-Thread <https://github.com/RT-Thread/rt-thread>`_: `repo <https://github.com/RT-Thread-packages/tinyusb>`_
-- **Mynewt** Due to the newt package build system, Mynewt examples are better to be on its `own repo <https://github.com/hathach/mynewt-tinyusb-example>`_
-
-License
-=======
-
-All TinyUSB sources in the `src` folder are licensed under MIT license. However, each file can be individually licensed especially those in `lib` and `hw/mcu` folder. Please make sure you understand all the license term for files you use in your project.

-================
-
-The board support code is only used for self-contained examples and testing. It is not used when TinyUSB is part of a larger project. It is responsible for getting the MCU started and the USB peripheral clocked with minimal of on-board devices
-
--  One LED : for status
--  One Button : to get input from user
--  One UART : optional for device, but required for host examples
