 #### Description
 
-The openEuler-1.0-LTS kernel for running on Raspberry Pi, located at branch [openEuler-1.0-LTS-raspi](https://gitee.com/openeuler/raspberrypi-kernel/tree/openEuler-1.0-LTS-raspi/).
+The 4.19.90 kernel for running on Raspberry Pi, branch master is the branch on development.
 
-This repository is built based on [openEuler-1.0-LTS kernel](https://gitee.com/openeuler/kernel/tree/openEuler-1.0-LTS/) and [Raspberry Pi kernel](https://github.com/raspberrypi/linux/tree/rpi-4.19.y).
+This repository is based on [4.19.90-2003.4.0](https://gitee.com/openeuler/kernel/tree/openEuler-1.0-LTS/) version kernel which is built into openEuler 20.03 LTS, and is merge with the 4.19.y branch of [Raspberry Pi kernel](https://github.com/raspberrypi/linux/tree/rpi-4.19.y).
