+Development Infrastructure
+==========================
+
+This document describes the development infrastructure used by the nalu-wind project.
+
+Docker Container
+----------------
+
+The docker container `ecpe4s/exawind-snapshot <https://hub.docker.com/r/ecpe4s/exawind-snapshot>`_
+is build by an external collaborator in the E4S project.
+Its definition is at https://gitlab.e4s.io/uo-public/exawind-snapshot.
+
+It is based on an Ubuntu with GCC on which spack-manager is used to install exawind+hypre+openfast.
+
+It is build and pushed to Dockerhub daily.
+
+Continuous Integration
+----------------------
+
+There are currently two different systems the continuously check the code of this project.
+
+GitHub Actions
+^^^^^^^^^^^^^^
+
+The `github actions workflow <https://github.com/Exawind/nalu-wind/blob/master/.github/workflows/ci.yml>`_
+runs on every pull request towards master as well as all commits on master.
+
+It does the following things:
+
+* Style Check of the CPP code using clang-format with clang version 13
+* Run the unit tests
+
+  * Uses the docker container to allow to reuse the third party libraries
+  * Rebuilds nalu-wind with the source from the commit on which the ci is run
+  * Run all test with `unit` in the label using ctest
+
+Daily Regression Tests
+^^^^^^^^^^^^^^^^^^^^^^
+
+Additionally, the project is tested more extensively on some machines at NREL.
+The results are collected at `CDash <https://my.cdash.org/index.php?project=Exawind>`_.
+For more info see :ref:`ref-testing-cdash`.
