+IAR Support
+-----------
+
+IAR Project Connection files are provided to import TinyUSB stack into your project.
+
+* A buldable project of your MCU need to be created in advance.
+
+
+ * Take example of STM32F0:
+
+ - You need `stm32l0xx.h`, `startup_stm32f0xx.s`, `system_stm32f0xx.c`.
+
+ - `STM32L0xx_HAL_Driver` is only needed to run examples, TinyUSB stack itself doesn't rely on MCU's SDKs.
+
+* Open `Tools -> Configure Custom Argument Variables` (Switch to `Global` tab if you want to do it for all your projects)
+ Click `New Group ...`, name it to `TUSB`, Click `Add Variable ...`, name it to `TUSB_DIR`, change it's value to the path of your TinyUSB stack,
+ for example `C:\\tinyusb`
+
+Import stack only
+^^^^^^^^^^^^^^^^^
+
+1. Open `Project -> Add project Connection ...`, click `OK`, choose `tinyusb\\tools\\iar_template.ipcf`.
+
+Run examples
+^^^^^^^^^^^^
+
+1. (Python3 is needed) Run `iar_gen.py` to generate .ipcf files of examples:
+
+ .. code-block::
+
+ cd C:\tinyusb\tools
+ python iar_gen.py
+
+2. Open `Project -> Add project Connection ...`, click `OK`, choose `tinyusb\\examples\\(.ipcf of example)`.
+ For example `C:\\tinyusb\\examples\\device\\cdc_msc\\iar_cdc_msc.ipcf`
