 This repository is a template for how to set up a reproducible python environment with GitHub.
 
 ## Python-packaging
 
 To be able to create a python package, we need a folder with the name of the package (in this repository `mypackage`), and a `pyproject.toml` file.
+
+
+## Make a repository citable
+The easiest way to make your repository citable is to add a `CITATION.cff` file to the repository, as it is supported by both 
+[Zenodo's](https://zenodo.org/) and it's [Github integration](https://docs.github.com/en/repositories/archiving-a-github-repository/referencing-and-citing-content) and [Github](https://docs.github.com/en/repositories/managing-your-repositorys-settings-and-features/customizing-your-repository/about-citation-files) itself.
+
+## Contributing
+
+Contributions are always welcome!
+
+See [CONTRIBUTING.md](CONTRIBUTING.md) for ways to get started.
+
+A good idea is to look at the [issue tracker](https://github.com/jorgensd/reproducibility/issues) and see if you can resolve any open issues.
+
+If you find a bug in the source code, please [open an issue](https://github.com/jorgensd/reproducibility/issues/new).
