Nine quick tips for software containerization

Example of container integration in a Nextflow workflow.
This code snippet demonstrates how containers can be specified for individual processes within a workflow management system. The container directive isolates the alignment tool (here, BWA version 0.7.17) in its own environment; other pipeline steps can use different containers. This modular approach allows updating a single tool without rebuilding the entire computational environment, improving both maintainability and reproducibility.
