Diem on GitHub

All source code is kept under Git control.

git clone git://github.com/diem-project/diem.git
cd diem
git submodule init
git submodule update

If you want to upgrade your project to the last Diem release, you need to modify the file:
config/ProjectConfiguration.class.php

/*
 * Include Diem  
 */  
require_once '/path/to/diem/dmCorePlugin/lib/core/dm.php';

Here you tell your project where Diem is.
Just replace path/to/diem by the path to the diem-5.0.0_* directory.

Then, open a command line in your project root dir and run:

php symfony dm:setup
