 # Build with buildroot toolchain
+
 you can build everything for the target device with buildroot:  
 https://github.com/haoict/TiniLinux/blob/master/README.md#build
 
 or build the toolchain only and build simple-terminal separately
+
 ```bash
 # build toolchain
-cd buildroot
-make O=../TiniLinux/output.arm64 BR2_EXTERNAL=../TiniLinux toolchain_arm64_defconfig
-cd ../TiniLinux
+cd TiniLinux
