+## development
+
+Komodo uses a Docker image as the base of the GitLab pipelines.
+
+That means that there is nothing to build apart from the source code of Komodo itself when running jobs.
+
+When the development environment needs to change, e.g. when the version of Rust is bumped in
+[`rust-toolchain.toml`](./rust-toolchain.toml), one shall run the following commands to push the new
+Docker image to the [_container registry_][gitlab.isae-supaero.fr:dragoon/komodo@containers].
