+# Automated Licensing Compliance Install
+
+As described in [Automated License Compliance]( {{< ref "automated-license-compliance.md" >}}) a check is performed on image creation to confirm the compliance with the terms that [Apertis may wish to avoid]( {{< ref "license-expectations.md" >}} ).
+
+To support this feature several pieces of software need to be installed.
+
+## FOSSology
+
+The recommended FOSSolgy setup consist in
+- FOSSology server
+- PostgreSQL database server
+- Apache HTTP server
+
+We recommend to build this setup trough a Docker installation as described in [FOSSolgy Docker installation](https://github.com/fossology/fossology/blob/master/README.md#docker)
+
+Bellow there is a sample Docker compose file to spawn the different services

+## Gitlab CI
+
+The license scanning process is triggered by Gitlab CI, which requires the latest version of the following recipes:
+
+- `ci-package-builder`
+- `apertis-docker-images`
+- `apertis-image-recipes`
+
+The following CI variables configure the parameters to connect with FOSSology sever
+- `FOSSOLOGY_URL`
+- `FOSSOLOGY_USERNAME`
+- `FOSSOLOGY_PASSWORD`
+
+## OBS
+
+The package build process is performed in OBS by running `debhelper`, which requires the version `12.1.1co1` or above.
