+# Download AGL Source Code
+
+The AGL source code and Yocto layers are maintained on the AGL Gerrit server. For information on how to create accounts for gerrit see Getting Started with AGL.
+
+## Prepare Repo Tool
+
+AGL Uses the Repo tool for managing repositories. First you need to setup layers of AGL. You can use the commands below to prepare Repo:
+```
+mkdir ~/bin
+export PATH=~/bin:$PATH
+curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
+chmod a+x ~/bin/repo
+```
+## Download Latest Stable Release
+
+To download all layers for the for the latest stable release, Blowfish 2.0.2:
+
+```
+repo init -b blowfish -m default_blowfish_2.0.2.xml -u https://gerrit.automotivelinux.org/gerrit/AGL/AGL-repo
+repo sync
+```
+
+## Download Latest on Blowfish Branch
+
+To download all layers on the current release branch which may be in the midst of testing or changes prior to the next stable release:
+```
+repo init -b blowfish -u https://gerrit.automotivelinux.org/gerrit/AGL/AGL-repo
+repo sync
+```
+## Download Master Branch
+
+To download all code from master:
+
+```
+repo init -u https://gerrit.automotivelinux.org/gerrit/AGL/AGL-repo
+repo sync
+```
+
+## Set up Build Environment
+
+Set up the development environment for the desired target hardware. AGL has created a set up script for defining the target build and desired optional features. To get a complete list of the options available run.
+
+```
+  $ source meta-agl/scripts/aglsetup.sh -h
+```
+
+Once you run aglsetup.sh with your desired paramaters, you can build any target desired.
+
+## Features supported by aglsetup
+
+Here is the list of features for AGL 2.0 that can be specified in the aglsetup.sh command line:
+
+- in **meta-agl**
+    * **agl-devel**: activate development options (empty root password, debugger, strace, valgrind …)

+- in **meta-agl-extra**
