I created some DOIs for citing VFI Toolkit. You are welcome to use VFI Toolkit without citing it, citation is not a requirement of use, but I will be grateful if you do 😃

To cite VFI toolkit: [https://doi.org/10.5281/zenodo.8136790](https://doi.org/10.5281/zenodo.8136790)  
The citation is essentially a pointer to the github repo for VFI Toolkit.

To cite the ‘Intro to Life-Cycle Models’: [https://doi.org/10.5281/zenodo.8136810](https://doi.org/10.5281/zenodo.8136810)

To cite the ‘Intro to OLG Models’: [https://doi.org/10.5281/zenodo.8136815](https://doi.org/10.5281/zenodo.8136815)

You can also [cite the paper announcing VFI Toolkit](https://doi.org/10.1007/s10614-015-9544-1), which is what people have done until now. But that article is getting a little out of date so I figured that being able to cite the toolkit directly would be a nicer alternative.

Some people had cited the intro to life-cycle models, so I figured I should provide a more formal way to do so.

If you want to create a DOI for your own code, check

Zenodo works very smoothly with github repos.
