Join us from March 13-16 2023 for the Nextflow and nf-core training event!

The training is entirely virtual and free and will cover the fundamentals of using Nextflow and nf-core. While the training will offer something for all skill levels it will be especially useful for those who are new to Nextflow and the nf-core community, or if you are thinking about joining the nf-core Hackathon (March 27-29, 2023) for the first time.

Prior knowledge of Nextflow is not required but will make it easier to understand new concepts.
