+Creating a new codestream
+=========================
+
+To create a new codestream follow these steps:
+
+1. Create a deployment branch. It must have the name
+   :py:attr:`~staging.bot.StagingBot.deployment_branch_name` and should contain
+   only a :file:`_config` file with the prjconf of the target project (usually
+   you can take the prjconf from the previous service pack, if applicable).
+
+2. Create the target project on OBS. This can be achieved via the bot command
+   ``setup_obs_project``:
+
+.. code-block:: shell
+
+   $ export OSC_USER=$MY_USER
+   $ export OSC_PASSWORD=$MY_PASS
+   $ poetry run scratch-build-bot \
+         --os-version $CODE_STREAM \
+         --branch-name="doesNotMatter" \
+         -vvvv setup_obs_project
+
+3. Add the new code stream to the github action files to the ``os_version``
+   list:
+   :file:`.github/workflows/obs_build.yml`
+   :file:`.github/workflows/update-deployment-branches.yml`
+   :file:`.github/workflows/update-cr-project.yml`
+   :file:`.github/workflows/cleanup-staging.yml`
+
+
+SLCC specific steps
+-------------------
+
+For SLCC we need to build the FTP trees (= repositories) ourselves. For that we
+must create the ``000*`` packages in the checked out project:
+
+.. code-block:: shell
+
+   $ cd devel:BCI:SLCC:$stream/
+
+   $ osc mkpac 000product
+   A    000product
+
+   $ osc mkpac 000release-packages
+   A    000release-packages
+
+   $ osc mkpac 000package-groups
+   A    000package-groups
+
+
+We only have to touch ``000package-groups`` directly, the remaining two are
+auto-generated using `pkglistgen
+<https://github.com/openSUSE/openSUSE-release-tools/blob/master/docs/pkglistgen.md>`_.
+
+
+python3 ./pkglistgen.py --verbose -A https://api.opensuse.org update_and_solve -p devel:BCI:SLCC:dynamic-developer -s target
