-## Via Container
-
-An [open container](<https://opencontainers.org/>) image (aka docker image) is built on
-[Dockerhub](<https://hub.docker.com/r/tskit/msprime>) for each release of
-msprime. Each image is [tagged](<https://hub.docker.com/r/tskit/msprime/tags>)
-with the corresponding release. For example, for msprime release 0.7.5, the
-corresponding image tag is `tskit/msprime:0.7.5`.
-
-To run a container, you can use [docker](<https://www.docker.com/>),
-[Singularity](<https://sylabs.io/singularity/>),
-[podman](<https://podman.io/>) or similar tools supporting docker images.
-
-### docker
-
-`docker` requires root privilege to run a container:
-
-```{code-block} bash
-
-$ sudo docker run -it tskit/msprime:<release> mspms 10 1 -T
-
-```
-
-### podman
-
-podman can run an msprime container without root privilege:
-
-```{code-block} bash
-
-$ podman run -it docker.io/tskit/msprime:<release> mspms 10 1 -T
-
-```
-
-### Singularity
-
-A docker image can also be converted to a Singularity container and
-then run without root privilege:
-
-```{code-block} bash
-
-$ singularity pull docker://tskit/msprime:<release> msprime-<release>.simg
-$ singularity exec msprime-<release>.simg mspms 10 1 -T
-
-```
-
-::::::{note}
-
-It is possible that your current environment may conflict with the environment in the singularity container.
-There are two workarounds:
-
-1. Ignore your home with the conflicting environment with `--contain` or `-H </new/path/to/home> -e`
-
-```{code-block} bash
-
-$ singularity shell --contain msprime-release-0.7.3.simg
-Singularity: Invoking an interactive shell within container...
-
-Singularity msprime-release-0.7.3.simg:~> python3
-Python 3.6.8 (default, Jan 14 2019, 11:02:34)

-Type "help", "copyright", "credits" or "license" for more information.
->>> import msprime
->>>
-
-```
-
-or use a different path as your home that does not have a conflicting environment
-
-```{code-block} bash
-
-$ singularity shell -H </new/path/to/home> -e msprime-release-0.7.3.simg
-Singularity: Invoking an interactive shell within container...

-
-2. In python get rid of your local path
