+The **STMicroelectronics B-L475E-IOT01A Board Support Pack (BSP)**:
+
+- Contains examples in *csolution format* for usage with the [CMSIS-Toolbox](https://github.com/Open-CMSIS-Pack/cmsis-toolbox/blob/main/docs/README.md) and the  [VS Code CMSIS Solution](https://marketplace.visualstudio.com/items?itemName=Arm.cmsis-csolution) extension.
+- Requires the [Device Family Pack (DFP) for the STM32L4 series](https://www.keil.arm.com/packs/stm32l4xx_dfp-keil).
+- Is configured with [STM32CubeMX](https://www.st.com/en/development-tools/stm32cubemx.html) for the Arm Compiler 6 (MDK).
+
+## Content in *csolution format*
+
+- [Examples/Blinky](https://github.com/Open-CMSIS-Pack/ST_B-L475E-IOT01A_BSP/tree/main/Examples/Blinky) shows the basic usage of this board.
