 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 (If required, this can be changed). The **master** branch is the one used for *stable* code. The **mock** branch is created in case that the developers want to carry out mock tests.
 
-Developers should not push any code directly to these two repositories but into temporal branches or forks based on them. Once the code is sufficiently tested within the temp branch, a merge to the corresponding *stable* branch can be requested.
