+Make sure you have done all the ''Preparations'' listed above before getting started.

+**Build U-Boot:**
+```shell
+$ cd PATH_YOUR_PROJECT
+$ cd bootloader/uboot-repo/
+$ ./mk kvim5 --fastboot-write --avb2 --vab
+```
+Gernerate images in this step:
+  * ''build/u-boot.bin.signed'': for onboard eMMC storage booting
+  * ''build/u-boot.bin.sd.bin.signed'': for external TF card booting
+**Build Linux Kernel:**
+```shell
+$ ./mk kvim5 -v common16-6.12 -jN
+```
+<WRAP important >
+Replace ''N'' with the actual number of threads on your own computer.
+</WRAP>
+**Build Android:**
+```shell
+$ cd PATH_YOUR_PROJECT
+$ . build/envsetup.sh
+$ lunch kvim5_arm64-bp4a-userdebug
+$ make -jN
+$ make -jN otapackage
+```
+Gernerate images in this step: ''out/target/product/kvim5/update.img''.
+<WRAP important >
+Replace ''N'' with the actual number of threads on your own computer.

+**Build Script Demo:**
+```sh demo.sh
+$ cat demo.sh
+#!/bin/bash
