-This material was originally presented as sample code here on GitHub and a separate blog post https://johnnado.com/pyqt-qtest-example/. The blog post has been migrated so that everything is unified here on GitHub.
+### Blog post for PyQt4
+
+This material was originally presented by John McGehee for PyQt4 on July 31, 2011, in a blog post on `voom.net` and later `johnnado.com`. Sample code was presented separately on BitBucket, then GitHub.
+
+### Unified on GitHub; blog post deprecated
+
+On May 18, 2023, everything was unified on GitHub by migrating the blog post to this README file per [issue #7](https://github.com/jmcgeheeiv/pyqttestexample/issues/7). The blog post URL was permanently redirected to this GitHub repository.
 
 The blog post accumulated comments containing useful solutions. These comments have been converted to GitHub issues:
 
-* A user asked **how to test event handlers**. Another user proposed a solution. The entire discussion appears in [issue #2](https://github.com/jmcgeheeiv/pyqttestexample/issues/2).

 * A user found a way to **test launching and accepting results from modal dialogs**. The entire discussion appears in [issue #4](https://github.com/jmcgeheeiv/pyqttestexample/issues/4).
 * A user asks for a good way to **test the `getSaveFileName()` dialog**. The entire discussion appears in [issue #5](https://github.com/jmcgeheeiv/pyqttestexample/issues/5).
