+[![pipeline status](https://git.stuvus.uni-stuttgart.de/ref-it/docker-overleaf-ldap/badges/main/pipeline.svg)](https://git.stuvus.uni-stuttgart.de/ref-it/docker-overleaf-ldap/-/pipelines?ref=main)
+
+This repository provides an OCI image for
+[Overleaf](https://github.com/overleaf/overleaf) bundled with
+[ldap-overleaf-sl](https://github.com/smhaller/ldap-overleaf-sl)
+to support LDAP authentication.
+One can use [Docker](https://www.docker.com/) in order to build the image,
+as follows.
+
+```sh
+docker build --build-arg BASE=docker.io/sharelatex/sharelatex:2.6.1 -t docker-overleaf-ldap .
+```
+
+## Build arguments
+
+The following arguments can be passed via `--build-args`.
+
+| Argument          | Default                                                               | Description                                                                                                                                            |
