### [Quick history](https://nf-co.re/about)
- [NGI](https://ngisweden.scilifelab.se/) had been developing analysis pipelines for years and using a set of standards
- This helped other group run the pipelines on their own
- Pipelines began to outgrow the `SciLifeLab/NGI` branding
- In late 2017,` nf-core` was created, thanks to Phil Ewels ([NGI](https://ngisweden.scilifelab.se/)), Alex Peltzer ([QBiC](https://portal.qbic.uni-tuebingen.de/portal/)), Sven Fillinger ([QBiC](https://portal.qbic.uni-tuebingen.de/portal/)) and Andreas Wilm ([A*STAR](https://www.a-star.edu.sg/))
- All relevant pipelines were moved to this new [GitHub organisation](https://github.com/nf-core)

- [Hackathons](https://nf-co.re/events/2022/hackathon-march-2022)
---
### What we want in our pipelines
- [Nextflow](https://www.nextflow.io/) based
- Common structure (based on our nf-core template)
- Stable release tags
- MIT license (can be used even in commercial settings)
- Using [biocontainers](https://biocontainers.pro/) (if possible)
- Continuous Integration testing ([GitHub Actions](https://github.com/features/actions))
- One pipeline per data type/usage ([lagom](https://www.atlasobscura.com/places/the-lagom-standard-measure))
---
### [Pipelines availability](https://nf-co.re/pipelines)
- Our website has pages for each pipeline that renders the documentation available on GitHub
- 33 released pipelines
- 27 in development
---
### [A companion tool](https://nf-co.re/tools)
- [nf-core launch](https://nf-co.re/tools#launch-a-pipeline) - Run pipeline with interactive prompts
- [nf-core download](https://nf-co.re/tools#downloading-pipelines-for-offline-use) - Download pipeline for offline use
- [nf-core create](https://nf-co.re/tools#creating-a-new-workflow) - Create a new pipeline from the template
- [nf-core lint](https://nf-co.re/tools#linting-a-workflow) - Check pipeline code against guidelines
- [nf-core modules](https://nf-co.re/tools/#modules) - Commands for dealing with DSL2 modules
---
### Configurations
All pipelines come with a default sensible configuration for a regular sized HPC
[nf-core/configs](https://github.com/nf-core/configs/) allows shared configurations between pipelines for a specific HPC
* cpus, time and memory requirements
* scheduler
* queues
* environments
* path to common references files
---
### [Modules](https://nf-co.re/modules)
Modules are the building stones of all DSL2 nf-core blocks.
Can be used outside nf-core as well.
---
### Demo
```
# Install Nextflow
curl -s https://get.nextflow.io | bash
# Run a nf-core pipeline with test data
nextflow run nf-core/sarek -r dev -profile test,docker
```
