Configure repo

In order to use Yocto build system, first you need to make sure that repo is properly installed on the machine:

...

Repo manages this for you by means of an XML based Manifest file. The Manifest file defines which repositories the project uses and links to appropriate revisions of each git repository, i.e where the upstream repositories reside and where they should be cloned locally. It is the manifest.xml (or default.xml) that determines which Git repositories and revisions repo will manage. This manifest.xml file is hosted in a Git repository along with all the other git repositories.

 Credential configuration

Note: it is also recommended to put credentials in .netrc when interacting with the repo.
