-CI/CD containerised environments
---------------------------------
-
-Beside the `kiwix-build` command line tool, Kiwix Build proposes
-[prepared compilation environments for multiple GNU/Linux
-systems](.github/ci_images/) too.
-
-These prepared environments include: compilers, binary toolchains and
-any third-party tool necessary to run the compilation toolchain. They
-don't contain pre-compiled library dependences build by kiwix-build, (like Xapian, Libicu,
-Libmicrohttps, ...) but it contains dependencies installed with package manager.
-
-These container images are necessary and intended to be used by Kiwix
-itself in many of its CI. But they are free to download et can be
-reused, although they can break anytime, therefore at your won risk.
-You can find them on
-[here](https://github.com/orgs/kiwix/packages?repo_name=kiwix-build).
