 Each package belongs to a separate Git repository. By default, there are two branches within each of the repositories: one called **master** and another one called **mock**. Both branches are protected and maintained by IRI (Although if required, this can be changed). The **master** branch is the one used for keeping the *stable* version of the code. The **mock** branch is created in case that the developers want to carry out mock tests.
