 ## Configuration 
 
+This fork of test-runner has a port of the JVM version to run in CLR; 
+this is in the clr-port branch.
+
+
+
 Include a dependency on this project in your `deps.edn`. You will
 probably wish to put it in the `test` alias:
 
 ```clojure
-;; v0.5.1
+;; v0.5.3
 :aliases {:test {:extra-paths ["test"]
                  :extra-deps {io.github.cognitect-labs/test-runner
