+## Mock Publication
+
+If the release workflow is changed, it is important to test the new workflow. This can be done by publishing to a local registry. The following steps will setup a local registry and configure npm to use it.
+
+```sh
+npm install -g verdaccio
+verdaccio --config ./devtools/verdaccio.yaml --listen=4873
+npm config set registry http://localhost:4873
+npm config set //localhost:4873/:_authToken fake
+```
+
+To test the release workflow on GitHub, the following step can be added to the workflow file.
+
+```yaml
+# TODO remove me when ready
+- name: Release to Verdaccio
+  run: |
+    npm install -g verdaccio
+    npm config set registry http://localhost:4873
+    npm config set //localhost:4873/:_authToken fake
+    nohup verdaccio --config ./devtools/verdaccio.yaml --listen=4873 >/dev/null 2>&1 &
+```
