+# Dockerfiles
+
+This directory contains the Dockerfiles that are used during the deployment
+of branch and PR environments for DPL CMS and for building source releases.
+
+the cli, nginx and php dockerfiles are used to generate the container-images
+that Lagoon uses in PR/Branch environments. These files mirrors the files used
+for production deployments in
+<https://github.com/danskernesdigitalebibliotek/dpl-platform/blob/main/infrastructure/dpladm/env-repo-template/>
+. Should you need to make modifications to these files, make sure to also make
+the changes to the production versions.
+
+`source.dockerfile` is used build and store a release of dpl-cms. For PR/branch
+environments the file is used as the first step in building the Lagoon images.
+The same file is used by the Github action that builds tagged releases of
+dpl-cms.
