+# seqeralabs/nf-aggregate: Contributing Guidelines
+
+Hi there!
+Many thanks for taking an interest in improving seqeralabs/nf-aggregate.
+
+We try to manage the required tasks for seqeralabs/nf-aggregate using GitHub issues, you probably came to this page when creating one.
+Please use the pre-filled template to save time.
+
+However, don't be put off by this template - other more general issues and suggestions are welcome!
+Contributions to the code are even more welcome ;)
+
+## Contribution workflow
+
+If you'd like to write some code for seqeralabs/nf-aggregate, the standard workflow is as follows:
+
+1. Check that there isn't already an issue about your idea in the [seqeralabs/nf-aggregate issues](https://github.com/seqeralabs/nf-aggregate/issues) to avoid duplicating work. If there isn't one already, please create one so that others know you're working on this
+2. [Fork](https://help.github.com/en/github/getting-started-with-github/fork-a-repo) the [seqeralabs/nf-aggregate repository](https://github.com/seqeralabs/nf-aggregate) to your GitHub account
+3. Make the necessary changes / additions within your forked repository following [Pipeline conventions](#pipeline-contribution-conventions)
+4. Use `nf-core schema build` and add any new parameters to the pipeline JSON schema (requires [nf-core tools](https://github.com/nf-core/tools) >= 1.10).
+5. Submit a Pull Request against the `dev` branch and wait for the code to be reviewed and merged
+
+If you're not used to this workflow with git, you can start with some [docs from GitHub](https://help.github.com/en/github/collaborating-with-issues-and-pull-requests) or even their [excellent `git` resources](https://try.github.io/).
+
+## Tests
+
+You have the option to test your changes locally by running the pipeline. For receiving warnings about process selectors and other `debug` information, it is recommended to use the debug profile. Execute all the tests with the following command:
+
+```bash
+nf-test test --profile debug,test,docker --verbose
+```
+
+When you create a pull request with changes, [GitHub Actions](https://github.com/features/actions) will run automatic tests.
+Typically, pull-requests are only fully reviewed when these tests are passing, though of course we can help out before then.
+
+There are typically two types of tests that run:
+
+### Lint tests
+
+`nf-core` has a [set of guidelines](https://nf-co.re/developers/guidelines) which all pipelines must adhere to.
+To enforce these and ensure that all pipelines stay in sync, we have developed a helper tool which runs checks on the pipeline code. This is in the [nf-core/tools repository](https://github.com/nf-core/tools) and once installed can be run locally with the `nf-core lint <pipeline-directory>` command.
+
+If any failures or warnings are encountered, please follow the listed URL for more documentation.
+
+### Pipeline tests
+
+Each `nf-core` pipeline should be set up with a minimal set of test-data.
+`GitHub Actions` then runs the pipeline on this data to ensure that it exits successfully.
+If there are any failures then the automated tests fail.
+These tests are run both with the latest available version of `Nextflow` and also the minimum required version that is stated in the pipeline code.
+
+## Patch
+
+:warning: Only in the unlikely and regretful event of a release happening with a bug.
+
+- On your own fork, make a new branch `patch` based on `upstream/master`.
+- Fix the bug, and bump version (X.Y.Z+1).
+- A PR should be made on `master` from patch to directly this particular bug.
+
+## Pipeline contribution conventions
+
+To make the seqeralabs/nf-aggregate code and processing logic more understandable for new contributors and to ensure quality, we semi-standardise the way the code and other contributions are written.
+
+### Adding a new step
+
+If you wish to contribute a new step, please use the following coding standards:
+
+1. Define the corresponding input channel into your new process from the expected previous process channel
+2. Write the process block (see below).
+3. Define the output channel if needed (see below).
+4. Add any new parameters to `nextflow.config` with a default (see below).
+5. Add any new parameters to `nextflow_schema.json` with help text (via the `nf-core schema build` tool).
+6. Add sanity checks and validation for all relevant parameters.
+7. Perform local tests to validate that the new code works as expected.
+8. If applicable, add a new test command in `.github/workflow/ci.yml`.
+9. Update MultiQC config `assets/multiqc_config.yml` so relevant suffixes, file name clean up and module plots are in the appropriate order. If applicable, add a [MultiQC](https://https://multiqc.info/) module.
+10. Add a description of the output files and if relevant any appropriate images from the MultiQC report to `docs/output.md`.
+
+### Default values
+
+Parameters should be initialised / defined with default values in `nextflow.config` under the `params` scope.
+
+Once there, use `nf-core schema build` to add to `nextflow_schema.json`.
+
+### Default processes resource requirements
+
+Sensible defaults for process resource requirements (CPUs / memory / time) for a process should be defined in `conf/base.config`. These should generally be specified generic with `withLabel:` selectors so they can be shared across multiple processes/steps of the pipeline. A nf-core standard set of labels that should be followed where possible can be seen in the [nf-core pipeline template](https://github.com/nf-core/tools/blob/master/nf_core/pipeline-template/conf/base.config), which has the default process as a single core-process, and then different levels of multi-core configurations for increasingly large memory requirements defined with standardised labels.
+
+The process resources can be passed on to the tool dynamically within the process with the `${task.cpus}` and `${task.memory}` variables in the `script:` block.
+
+### Naming schemes
+
+Please use the following naming schemes, to make it easy to understand what is going where.
+
+- initial process channel: `ch_output_from_<process>`
+- intermediate and terminal channels: `ch_<previousprocess>_for_<nextprocess>`
+
+### Nextflow version bumping
+
+If you are using a new feature from core Nextflow, you may bump the minimum required version of nextflow in the pipeline with: `nf-core bump-version --nextflow . [min-nf-version]`
+
+### Images and figures
+
+For overview images and other documents we follow the nf-core [style guidelines and examples](https://nf-co.re/developers/design_guidelines).
+
+## GitHub Codespaces
+
+This repo includes a devcontainer configuration which will create a GitHub Codespaces for Nextflow development! This is an online developer environment that runs in your browser, complete with VSCode and a terminal.
+
+To get started:
+
+- Open the repo in [Codespaces](https://github.com/seqeralabs/nf-aggregate/codespaces)
+- Tools installed
+  - nf-core
+  - Nextflow
+
+Devcontainer specs:
+
+- [DevContainer config](.devcontainer/devcontainer.json)
