 Quick Start
 ===========
 
 In order to build one of the sample apps, you need to set a few environment
-variables:
-```
-export BL60X_SDK_PATH=/path/to/this/repo
-export CONFIG_CHIP_NAME=bl602
-```
-Then go to the sample directory of interest and call `make`, for example:
-```
-cd customer_app/bl602_boot2
-make
-```
-Call
-```
-make CONFIG_TOOLPREFIX=riscv64-linux-gnu-
-```
-for bypassing the bundled crosscompiler and using your distribution's own crosscompiler.

 There is a linker script (written in python) at `image_conf/flash_build.py`.
-To run this, you need to specify the application and the target, for example:
-```
-python3 flash_build.py bl602_boot2 bl602

 Hardware
 =========
 
-BL602 is a 32-bit RISC-V based combo chipset supporting Wi-Fi and BLE (Bluetooth Low Energy). The chip is made by `Nanjing-based Bouffalo Lab <https://www.bouffalolab.com/bl602>`_ for ultra-low-power applications.
-In terms of price range and feature set, the chip is competing against `Espressif ESP8266 <https://www.espressif.com/en/products/socs/esp8266>`_
