 ## Contribution workflow
-If you'd like to write some code for nf-core/nascent, the standard workflow
-is as follows:
 
-1. Check that there isn't already an issue about your idea in the
-   [nf-core/nascent issues](https://github.com/nf-core/nascent/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 the [nf-core/nascent repository](https://github.com/nf-core/nascent) to your GitHub account
-3. Make the necessary changes / additions within your forked repository
-4. Submit a Pull Request against the `dev` branch and wait for the code to be reviewed and merged.
+If you'd like to write some code for nf-core/nascent, the standard workflow is as follows:

+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

 ## Tests
-When you create a pull request with changes, [Travis CI](https://travis-ci.org/) will run automatic tests.
+
+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
-The nf-core has a [set of guidelines](http://nf-co.re/guidelines) which all pipelines must adhere to.
+### 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.
-Travis CI then runs the pipeline on this data to ensure that it exists successfully.

+
+## 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.
 
 ## Getting help
-For further information/help, please consult the [nf-core/nascent documentation](https://github.com/nf-core/nascent#documentation) and don't hesitate to get in touch on the pipeline channel on [Slack](https://nf-core-invite.herokuapp.com/).
+
+For further information/help, please consult the [nf-core/nascent documentation](https://nf-co.re/nascent/usage) and don't hesitate to get in touch on the nf-core Slack [#nascent](https://nfcore.slack.com/channels/nascent) channel ([join our Slack here](https://nf-co.re/join/slack)).
+
+## Pipeline contribution conventions
+
+To make the nf-core/nascent 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 `${task.cpu}` and `${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).
