Since this project has evolved to a point where there's so many sub-projects, it would make life easier for everyone to have a tool to download all projects in this organization.
To get started on this project, you will need to download repo from Google.
$ mkdir ~/bin
$ echo "PATH=~/bin:$PATH" >> ~/.bashrc
$ source ~/.bashrc
$ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
$ chmod a+x ~/bin/repo
After that, create a working directory and simply initiazlize your local repository.
$ mkdir PAS
$ cd PAS
$ repo init -u https://github.com/ASDFDev/Repo-Manifest.git
$ repo sync
Note that you will need a macOS device to be able to build the iOS clients.
