 ## Citing GRASS Software
 
+Please cite GRASS when using the software in your work. Here are some choices to
+cite the overall software project, a specific GRASS version being used used, or
+the documentation to allow reproducability:
+
+### The GRASS GIS project as an evolving software project, independent of a specific software release
+
+- GRASS Development Team, 2026. Geographic Resources Analysis Support System
+  (GRASS) Software, Open Source Geospatial Foundation. https://grass.osgeo.org,
+  [![DOI](https://zenodo.org/badge/DOI/10.5281/zenodo.5176030.svg)](https://doi.org/10.5281/zenodo.5176030)
+
+Use the concept DOI
 [![DOI](https://zenodo.org/badge/DOI/10.5281/zenodo.5176030.svg)](https://doi.org/10.5281/zenodo.5176030)
+when
+
+- referring to GRASS GIS in general (e.g., in introductions or background sections)
+- describing workflows where the exact version is not critical
+- citing GRASS as a long-term research tool or infrastructure
+
+The concept DOI will always resolve to the latest version of GRASS and provide a
+stable reference to the software project over time.
 
-Please cite GRASS when using the software in your work. Here are some choices
-depending on the version used:
+### Specific GRASS software releases
 
-- GRASS Development Team, 2025. Geographic Resources Analysis Support System (GRASS)
-Software, Version 8.4. Open Source Geospatial Foundation. https://grass.osgeo.org, DOI: 10.5281/zenodo.5176030
+#### GRASS 8.x - GRASS 7.8.6

-Software, Version 7.8. Open Source Geospatial Foundation. https://grass.osgeo.org, DOI: 10.5281/zenodo.5176030
+Each GRASS release has its own version DOI identifying a precise, archived
+snapshot of the software (e.g., a specific 8.x release). All version DOI are
+linked to the concept DOI of the GRASS project.
