Workflow Diagrams
It is often useful to have simplified diagrams that outline the main functionality and steps of a pipeline. This helps new users get an overview of a workflow when visiting a pipeline webpage or repository for the first time.
Most workflow diagrams are made by hand using vector image editors such as the open-source Inkscape or commercial suites such as Adobe Illustrator. Useful tools for collaborative prototyping include Google Drawings or LucidChart. All examples and components below can be opened in these editors, and various parts borrowed and/or modified as necessary.
The components are also made available on bioicons, which offers extensions for Inkscape and draw.io to directly import them there.
Examples
See below for some examples of nf-core workflow schematics that can be re-used and modified for your own pipeline.

Use draw.io
The web app draw.io helps you create, render and export different diagrams including metro-maps. For even more convenience you can use the following asset library nf-core xml item library. It contains all of the components from the cheatsheet above. To import it to draw.io use “File / Open library from / URL…” and paste:
