+$ cd WORKING_DIRECTORY
+```
+. Run ''repo init'' to download the manifest repository first.
+```shell
+$ repo init -u https://github.com/khadas/android_manifest.git -b khadas-edge2-android12
+```
+. Run ''repo sync'' to pull down the Android source tree.
+```shell
+$ repo sync -j4
+```
+The initial sync operation may take an hour or more to complete.
+<WRAP info >
+You might need to run above command repeatly if it fails halfway. Or you can try with this script instead:
+```bash sync_helper.sh
+#!/bin/bash
+repo sync -j4
+while [ $? = 1 ]; do
+	echo "Sync failed, repeat again:"
+	repo sync -j4
+done
+```
+If needed, press ''Ctrl''+''C'' to quit.
