+#### Seed from internal path
+
+This image can load ldif and schema files at startup from an internal path. This is useful if a continuous integration service mounts automatically the working copy (sources) into a docker service, which has a relation to the ci job.
+
+For example: Gitlab is not capable of mounting custom paths into docker services of a ci job, but gitlab automatically mounts the working copy in every service container. So the working copy (sources) are accessible under `/builds` in every services
+of a ci job. The path to the working copy can be obtained via `${CI_PROJECT_DIR}`. See also: https://docs.gitlab.com/runner/executors/docker.html#build-directory-in-service
+
+This may also work with other CI services, if they automatically mount the working directory to the services of a ci job like gitlab ci does.
+
+In order to seed ldif or schema files from internal path you must set the specific environment variable `LDAP_SEED_INTERNAL_LDIF_PATH` and/or `LDAP_SEED_INTERNAL_SCHEMA_PATH`. If set this will copy any *.ldif or *.schema file into the default seeding
+directories of this image.
+
+Example variables defined in gitlab-ci.yml:
+
+	variables:
+		LDAP_SEED_INTERNAL_LDIF_PATH: "${CI_PROJECT_DIR}/docker/openldap/ldif"
+		LDAP_SEED_INTERNAL_SCHEMA_PATH: "${CI_PROJECT_DIR}/docker/openldap/schema"
+
 ### Use an existing ldap database
 
 This can be achieved by mounting host directories as volume.
