+====== VIM3/3L Download Android Source Code ======
+The Android Source Tree of our Khadas VIM3 are hosted on [[https://www.github.com/khadas|Github]]. There are many different repositories.Walk through the steps below to download the Source Code.
+===== Steps =====
+Firstly, install ''git-lfs'' tool for downloading Android SDK.
+```shell
+$ mkdir git_lfs
+$ cd git_lfs
+$ wget https://github.com/git-lfs/git-lfs/releases/download/v2.3.4/git-lfs-linux-amd64-2.3.4.tar.gz
+$ tar xvzf git-lfs-linux-amd64-2.3.4.tar.gz
+$ cd git-lfs-2.3.4
+$ sudo ./install.sh
+$ git lfs install
+```
+Create an empty directory to hold your working files:
+```shell
+$ mkdir -p WORKING_DIRECTORY
+$ cd WORKING_DIRECTORY
+```
+Run ''repo init'' to download the manifest repository first:
+**android 9.0 64 bit:**
+```shell
+$ repo init -u https://github.com/khadas/android_manifest.git -b khadas-vim3-p-64bit
+```
+<WRAP tip >
+Needed after repo sync go to the following directory and execute the git lfs pull command to pull large files. Otherwise, compilation will report an error
+```shell
+device/khadas
+```
+```shell
+/users/amlogic/vim3/vim3_64bit$ cd device/khadas/
+/users/amlogic/vim3/vim3_64bit/device/khadas$ git lfs pull
+```
+</WRAP>
+**android 9.0 32 bit:**
+```shell
+$ repo init -u https://github.com/khadas/android_manifest.git -b khadas-vims-pie
+```
+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 tip >
+You might need to run above command repeatly if it fails halfway. Or you can try with this script instead.
+```shell
+#!/bin/bash
+repo sync -j4
+while [ $? = 1 ]; do
+	echo "Sync failed, repeat again:"
+	repo sync -j4
+done
+```
+If needed, press ''Ctrl''+''\'' to quit.
+</WRAP>
+Begin a new branch for development:
+```shell
+$ repo start <BRANCH_NAME> --all
+```
