built on top of [Podman](https://podman.io/) and other standard container
technologies from [OCI](https://opencontainers.org/).
The toolbox container is a fully *mutable* container; when you see
`yum install ansible` for example, that's something you can do inside your
toolbox container, without affecting the base operating system.
This is particularly useful on
[OSTree](https://ostree.readthedocs.io/en/latest/) based operating systems like
[Fedora CoreOS](https://coreos.fedoraproject.org/) and
[Silverblue](https://silverblue.fedoraproject.org/). The intention of these
systems is to discourage installation of software on the host, and instead
install software as (or in) containers.
install software as (or in) containers — they mostly don't even have package
managers like DNF or YUM. This makes it difficult to set up a development
environment or install tools for debugging in the usual way.
However, this tool doesn't *require* using an OSTree based system — it
works equally well if you're running e.g. existing Fedora Workstation or
Server, and that's a useful way to incrementally adopt containerization.
Toolbox solves this problem by providing a fully mutable container within
which one can install their favourite development and debugging tools, editors
and SDKs. For example, it's possible to do `yum install ansible` without
affecting the base operating system.

The toolbox environment is based on an [OCI](https://www.opencontainers.org/)

create a toolbox container that seamlessly integrates with the rest of the
operating system.
