-  2) When you are viewing the record, look for the **Versions** box
-     in the right-sidebar. Here are listed all versions (including
-     older versions).
-
-  3) Select and click the version-specific DOI that matches the

+* **and** a citation to the `Zenodo record
+  <https://zenodo.org/records/10080667>`__ which includes a DOI for
+  the version of the software you used in your analyses. Citing this
+  record and DOI supports reproducibility by allowing researchers to
+  to determine the exact version of PyPop used in any particular
+  analysis. In addition, it allows retrieval of long-term software
+  source-code archives, independent of the original developers.
+
+  Here's how to cite the correct version:
+
+  * If you have PyPop version 1.1.2 or later, currently installed, you
+    can run:
+
+    .. code-block:: shell
+
+       pypop --citation
+
+    which outputs the Zenodo record citation in the simple "APA"
+    format (you can also choose from BibTeX, EndNote, RIS and other
+    formats, see the section on `command-line interfaces
+    <http://pypop.org/docs/guide-chapter-usage.html#command-line-interfaces>`_
+    in the *User Guide* for more details).
+
+  * If you do not have PyPop installed, have a release of PyPop
+    earlier than 1.1.2, or otherwise want to obtain the DOI and
+    citation for specific versions, follow these steps:
+
+    1) First visit the DOI for the overall Zenodo record:
+       `10.5281/zenodo.10080667
