+# Continuous Integration
+
+## Overview
+
+We continuously test against recent versions of the following software pieces:
+- Ubuntu
+- OpenFOAM
+- SmartSim
+- Database backend (redis, or keydb)
+
+In particular, by testing on multiple versions of Ubuntu distribution, we make sure
+things work on the default toolchain versions (Compilers, system OpenMPI, ..., etc)
+
+We use [Github Container Registry](https://ghcr.io/) to store the Docker images necessary for
+CI workflows.
+
+## Instructions
+
+> [!NOTE]
+> You will want to install ansible (locally) to build the images easily: `pip install ansible`.
+> Each image is a little than 2GB so make sure you have enough disk space.
+
+1. In [docker/build.yml](docker/build.yml) file, add the new version in the relevant fact task.
+   - For example, to add a new version of OpenFOAM, add the version to `openfoam_versions`
+   - Then run `ansible-playbook build.yml --extra-vars "username=github_user  token=$GITHUB_TOKEN`
+     to build the corresponding image and push it.
+     - When building the images locally, you can speed the process by removing other software versions
+     and keeping only the new one
+2. In [.github/workflows/ci.yaml](.github/workflows/ci.yaml) file, add the new version in the relevant
+   `strategy` section.
+   - For example, to add a new version of OpenFOAM, add the version to `jobs.build.strategy.matrix.openfoam_version`
+   - Then commit the changes to the repository.
