+## Introduction
+
+QC starts using a new format of XBL config since 8450 platforms. The new format designed for it is to store some
+important configurations like `XBL DTB`, `CPR`, and `DCB`.  
+This tool is aim to extract those files from the XBL config.
+:::tip
+This tool only works on SM8450 and subsequent platforms.
+:::
+
+## How to use
+
+- Just run it in a terminal will be fine.
+- xbl_config.img is also acceptable.
+
+```
+Usage: <Path to xbl_config.elf> <Output Directory>
+```
+
+## Build
+- Need cmake and C toolchain.
+```
+git clone https://github.com/woa-msmnile/XBLConfigReader --depth=1
+cd XBLConfigReader
+mkdir build && cd build
+cmake -S .. && cmake --build .
+```
