 Finally, glean will handle ssh-keypair-injection from config
 drive if cloud-init is not installed.
+
+Chosing glean installation source
+---------------------------------
+
+By default glean is installed using pip using the latest release on pypi.
+It is also possible to install glean from a specified git repository
+location. This is useful for debugging and testing new glean changes
+for example. To do this you need to set these variables::
+
+  DIB_INSTALLTYPE_simple_init=repo
+  DIB_REPOLOCATION_glean=/path/to/glean/repo
+  DIB_REPOREF_glean=name_of_git_ref
+
+For example to test glean change 364516 do::
+
+  git clone https://git.openstack.org/openstack-infra/glean /tmp/glean
+  cd /tmp/glean
+  git review -d 364516
+  git checkout -b my-test-ref
+
+Then set your DIB env vars like this before running DIB::
+
+  DIB_INSTALLTYPE_simple_init=repo
+  DIB_REPOLOCATION_glean=/tmp/glean
+  DIB_REPOREF_glean=my-test-ref

+Base element for creating minimal SUSE-based images
+
+This element is incomplete by itself so you probaby want to use it along
+with the opensuse-minimal one. It requires 'zypper' to be installed on the
+host.
+
+Repositories
+------------
+
+This element expects the `ZYPPER_REPOS` variable to be exported by the
+operating system element. This variable contains repository mappings in 
+the following format: `${repo_name}==>${repo_url}`. For example::
+
+ ZYPPER_REPOS="update=>http://download.opensuse.org/update/leap/42.1/oss/ "
+ ZYPPER_REPOS+="oss=>http://download.opensuse.org/distribution/leap/42.1/repo/oss/"
