About CITATION files
You can add a CITATION.cff file to the root of a repository to let others know how you would like them to cite your work. The citation file format is plain text with human- and machine-readable citation information.
Example CITATION.cff file:
cff-version: 1.2.0
message: "If you use this software, please cite it as below."
authors:
- family-names: "Lisa"
given-names: "Mona"
orcid: "https://orcid.org/0000-0000-0000-0000"
- family-names: "Bot"
given-names: "Hew"
orcid: "https://orcid.org/0000-0000-0000-0000"
title: "My Research Software"
version: 2.0.4
doi: 10.5281/zenodo.1234
date-released: 2017-12-18
url: "https://github.com/github-linguist/linguist"
The GitHub citation prompt on your repository will show the example CITATION.cff content in these formats:
APA
Lisa, M., & Bot, H. (2017). My Research Software (Version 2.0.4) [Computer software]. https://doi.org/10.5281/zenodo.1234
BibTeX
@software{Lisa_My_Research_Software_2017,
author = {Lisa, Mona and Bot, Hew},
doi = {10.5281/zenodo.1234},
month = {12},
title = {{My Research Software}},
url = {https://github.com/github-linguist/linguist},
version = {2.0.4},
year = {2017}
}
Note the example above produces a software citation (that is, @software type in BibTeX rather than @article).
For more information, see the Citation File Format website.
When you add a CITATION.cff file to the default branch of your repository, a link is automatically added to the repository landing page in the right sidebar, with the label "Cite this repository." This makes it easy for other users to cite your software project, using the information you've provided.
Citing something other than software
If you would prefer the GitHub citation information to link to another resource such as a research article, then you can use the preferred-citation override in CFF with the following types.
| Resource | CFF type | BibTeX type | APA annotation |
|---|---|---|---|
| Journal article/paper | article | @article | Not applicable |
| Book | book | @book | Not applicable |
| Booklet (bound but not published) | pamphlet | @booklet | Not applicable |
| Conference article/paper | conference-paper | @inproceedings | [Conference paper] |
| Conference proceedings | conference, proceedings | @proceedings | Not applicable |
| Data set | data, database | @misc | [Data set] |
| Magazine article | magazine-article | @article | Not applicable |
| Manual | manual | @manual | Not applicable |
| Misc/generic/other | generic, any other CFF type | @misc | Not applicable |
| Newspaper article | newspaper-article | @article | Not applicable |
| Software | software, software-code, software-container, software-executable, software-virtual-machine | @software | [Computer software] |
| Report/technical report | report | @techreport | Not applicable |
| Unpublished | unpublished | @unpublished | Not applicable |
Extended CITATION.cff file describing the software, but linking to a research article as the preferred citation:
cff-version: 1.2.0
message: "If you use this software, please cite it as below."
authors:
- family-names: "Lisa"
given-names: "Mona"
orcid: "https://orcid.org/0000-0000-0000-0000"
- family-names: "Bot"
given-names: "Hew"
orcid: "https://orcid.org/0000-0000-0000-0000"
title: "My Research Software"
version: 2.0.4
doi: 10.5281/zenodo.1234
date-released: 2017-12-18
url: "https://github.com/github-linguist/linguist"
preferred-citation:
type: article
authors:
- family-names: "Lisa"
given-names: "Mona"
orcid: "https://orcid.org/0000-0000-0000-0000"
- family-names: "Bot"
given-names: "Hew"
orcid: "https://orcid.org/0000-0000-0000-0000"
doi: "10.0000/00000"

month: 9
start: 1 # First page number
end: 10 # Last page number
title: "My awesome research software"
issue: 1

year: 2021
The example CITATION.cff file above will produce the following outputs in the GitHub citation prompt:
APA
Lisa, M., & Bot, H. (2021). My awesome research software. Journal Title, 1(1), 1. https://doi.org/10.0000/00000
BibTeX
@article{Lisa_My_awesome_research_2021,
author = {Lisa, Mona and Bot, Hew},
doi = {10.0000/00000},
journal = {Journal Title},
month = {9},
number = {1},
pages = {1--10},
title = {{My awesome research software}},
volume = {1},
year = {2021}
}
Citing a dataset
If your repository contains a dataset, you can set type: dataset at the top level of your CITATION.cff file to produce a data citation string output in the GitHub citation prompt.
Other citation files
The GitHub citation feature will also detect a small number of additional files that are often used by communities and projects to describe how they would like their work to be cited.
GitHub will link to these files in the Cite this repository prompt, but will not attempt to parse them into other citation formats.
# Note these are case-insensitive and must be in the root of the repository

CITATION.bib

# CITATION files for R packages are typically found at inst/CITATION

Citation formats
We currently support APA and BibTeX file formats.
Are you looking for additional citation formats? GitHub uses a Ruby library, to parse the CITATION.cff files. You can request additional formats in the ruby-cff repository, or contribute them yourself.
