 `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.

 ## Getting help
 
 For further information/help, please consult the [nf-core/scflow documentation](https://nf-co.re/scflow/usage) and don't hesitate to get in touch on the nf-core Slack [#scflow](https://nfcore.slack.com/channels/scflow) channel ([join our Slack here](https://nf-co.re/join/slack)).
+
+## Pipeline contribution conventions
+
+To make the nf-core/scflow 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 flags/options to `nextflow.config` with a default (see below).
+5. Add any new flags/options to `nextflow_schema.json` with help text (with `nf-core schema build`).
+6. Add any new flags/options to the help message (for integer/text parameters, print to help the corresponding `nextflow.config` parameter).
+7. Add sanity checks for all relevant parameters.
+8. Add any new software to the `scrape_software_versions.py` script in `bin/` and the version command to the `scrape_software_versions` process in `main.nf`.
+9. Do local tests that the new code works properly and as expected.
+10. Add a new test command in `.github/workflow/ci.yml`.
+11. If applicable add a [MultiQC](https://https://multiqc.info/) module.
+12. Update MultiQC config `assets/multiqc_config.yaml` so relevant suffixes, name clean up, General Statistics Table column order, and module figures are in the right order.
+13. Optional: Add any descriptions of MultiQC report sections and output files 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]`
+
+### Software version reporting
+
+If you add a new tool to the pipeline, please ensure you add the information of the tool to the `get_software_version` process.
+
+Add to the script block of the process, something like the following:
+
+```bash
+<YOUR_TOOL> --version &> v_<YOUR_TOOL>.txt 2>&1 || true
+```
+
+or
+
+```bash
+<YOUR_TOOL> --help | head -n 1 &> v_<YOUR_TOOL>.txt 2>&1 || true
+```
+
+You then need to edit the script `bin/scrape_software_versions.py` to:
+
+1. Add a Python regex for your tool's `--version` output (as in stored in the `v_<YOUR_TOOL>.txt` file), to ensure the version is reported as a `v` and the version number e.g. `v2.1.1`
+2. Add a HTML entry to the `OrderedDict` for formatting in MultiQC.
+
+### 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).
