Mainly by creating or updating software packages in RPM binary format using source code archives taken from upstream external sources. The packages are made available in folders called repositories or channels.

Some components are internally developed with the help of the git distributed development system. openmamba makes its own git server available to allow the distributed development of these components.

HOW CAN I TAKE PART TO THE DEVELOPMENT?
Packages creation is made simpler and standard by using the autospec tool. Some practice is recommended by following the instructions in the wiki page.

openmamba has an automatic update and porting build system which developers may consult to find and work on manual corrections needed to update distribution components.

HOW DO I ADD A CHANNEL TO MY SYSTEM?
In order to get updates from a channel you need to enable it in the Software sources settings dialog of the openmamba packages management tool. A channel can be as well enabled by command line by issuing the following command:

pkcon repo-enable channel_name

• the devel trunk channel contains the whole main distribution with the exception of big games;
• devel-games is a branch of the devel channel containing big games;
• devel-makedist is a transitory channel used to automatically port packages to all architectures.

See the openmamba resources database for a list of system reserved uid and gid's.
See the groups database for the list of groups to use for RPM packages classification.
See the licenses database for a list of approved licence for Open Source software in openmamba.

Two or more openmamba developers can join to form a group for openmamba and open source development.
