 ## Requests for Comment
-The ISIS project uses a Request for Comment (RFC) model whereby major potential changes to the code base, data area, or binary delivery process are proposed, iterated on by any interested parties, and potentially adopted. Right now, RFCs are being housed in this repository's [wiki](https://github.com/USGS-Astrogeology/ISIS3/wiki) with associated discussions occurring on [astrodiscuss](https://astrodiscuss.usgs.gov).

+## Citing ISIS
+
+The badge at the top of this README lists the DOI of the most recent ISIS version.  As of 05/09/2024, the latest release of ISIS is version 8.0.3, and its DOI is [`10.5066/P13YBMZA`](https://doi.org/10.5066/P13YBMZA).
+
+The [Releases Page on GitHub](https://github.com/DOI-USGS/ISIS3/releases) lists the DOI for each version of ISIS.  Older versions may be listed on [Zenodo](https://doi.org/10.5281/zenodo.2563341).  It is good practice to cite the version of the software being used by the citing work, so others can reproduce your exact results.

-## Citing ISIS
-This project uses a [Zenodo](https://zenodo.org) generated DOI. The badge at the top of this README links to the DOI for the [latest release](https://doi.org/10.5281/zenodo.2563341). It is [good practice](https://help.zenodo.org) (See 'Which DOI Should I Use in Citations?') to cite the version of the software being used by the citing work. To obtain this DOI, one can follow the [link to the latest version](https://doi.org/10.5281/zenodo.2563341) and then check the right sidebar area titled **Versions** for a listing of all ISIS versions that currently have a Zenodo DOI.
