+# Using AMICI inside containers
+
+AMICI docker images are regularly published to
+https://hub.docker.com/r/dweindl/amici.
+
+## Docker / Podman
+
+The commands below are for use with Docker. When using Podman, just replace
+`docker` by `podman`.
+
+### Create an image
+
+In the AMICI base directory run:
+
+```bash
+git archive -o container/amici.tar.gz --format=tar.gz HEAD
+cd container && docker build -t $USER/amici:latest .
+```
+Note that this will include files from the last commit, but no uncommitted
+changes.  
+
+### Pull published image
+
+```bash
+docker pull dweindl/amici:latest
+```
+
+## Singularity / Apptainer
+
+### Create an image
+
+In the AMICI base directory run:
+
+```bash
+# prepare amici files to be copied to the image
+# Note that this will include files from the last commit, but no uncommitted
+# changes.  
+git archive -o container/amici.tar.gz --format=tar.gz HEAD
+# install spython if necessary
+test -x "$(command -v spython)" || pip install spython
+# convert Dockerfile to singularity/apptainer definition using spython
+(cd container/ && spython recipe Dockerfile amici.def)
+# build image
+(cd container/ && singularity build amici.sif amici.def)
+```
+
+### Pull published image
+
+```bash
+singularity pull docker://dweindl/amici:latest
+```
