The module files hosted in this repository define a set of processes for software tools such as `fastqc`, `bwa`, `samtools` etc. This allows you to share and add common functionality across multiple pipelines in a modular fashion.
We have written a helper command in the `nf-core/tools` package that uses the GitHub API to obtain the relevant information for the module files present in the `software/` directory of this repository. This includes using `git` commit hashes to track changes for reproducibility purposes, and to download and install all of the relevant module files.

#### Naming conventions
- The directory structure for the module name must be all lowercase e.g. `software/bwa/mem/`. The name of the software (i.e. `bwa`) and tool (i.e. `mem`) MUST be all one word.
- The directory structure for the module name must be all lowercase e.g. [`software/bwa/mem/`](software/bwa/mem/). The name of the software (i.e. `bwa`) and tool (i.e. `mem`) MUST be all one word.
- The process name in the module file MUST be all uppercase e.g. `process BWA_MEM {`. The name of the software (i.e. `BWA`) and tool (i.e. `MEM`) MUST be all one word separated by an underscore.
- All parameter names MUST follow the `snake_case` convention.
- All function names MUST follow the `camelCase` convention.

The features offered by Nextflow DSL2 can be used in various ways depending on the granularity with which you would like to write pipelines. Please see the listing below for the hierarchy and associated terminology we have decided to use when referring to DSL2 components:
- *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`. At present, this repository has been created to only host atomic module files that should be added to the `software/` directory along with the required documentation 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 although this may change in the future since well-written sub-workflows will be the most powerful aspect of DSL2.
- *Workflow*: What DSL1 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 DSL1, or by using a combination of DSL2 individual modules and sub-workflows.
