 * *Module*: A `process`that can be used within different pipelines and is as atomic as possible i.e. cannot be split into another module. An example of this would be a module file containing the process definition for a single tool such as `FastQC`. This repository has been created to only host atomic module files that should be added to the `tools` sub-directory along with the required documentation, software and tests.
 * *Sub-workflow*: A chain of multiple modules that offer a higher-level of functionality within the context of a pipeline.  For example, a sub-workflow to run multiple QC tools with FastQ files as input. Sub-workflows should be shipped with the pipeline implementation and if required they should be shared amongst different pipelines directly from there. As it stands, this repository will not host sub-workflows.
-* *Workflow*: What DSL 1 users would consider an end-to-end pipeline. For example, from one or more inputs to a series of outputs. This can either be implemented using a large monolithic script as with DSL 1, or by using a combination of DSL 2 individual modules and sub-workflows.
