All new recipes will be hosted on my quay.io repository.
Directories group recipes for a certain theme. Each program has it's own dedicated directory within each theme. Subsequently, each version of a program also has it's own subdirectory with a Dockerfile.
In general, I only create a recipe if a program does not have an officially-supported container or there is no Conda package available for it.
For previous Singularity recipes, check the repository commit history.
