+## versioninfo
+
+By default, only a brief version identifier is printed in the run log. You can display the full `versioninfo` by adding `show-versioninfo`.
+Here's an example that prints this information just for `nightly`:
+
+```yaml
+    - uses: julia-actions/setup-julia@v1
+      with:
+        version: ${{ matrix.version }}
+        arch: ${{ matrix.arch }}
+        show-versioninfo: ${{ matrix.version == 'nightly' }}
+ ```
+ 
+You use `'true'` if you want it printed for all Julia versions.
