+To test your changes, you can convert the Bazel Docs Devsite into a Hugo website running this command
+```bash
+root@7feab7b056d2:/app# python /app/cli.py convert --source /app/work/bazel-source/site/en/ --output /app/docs/
+```
+
+Add the modules needed (mainly Docsy)
+```bash
+cd /app/docs
+hugo mod init github.com/alan707/bazel-docs && \
+    hugo mod get github.com/google/docsy@v0.12.0 && \
+    hugo mod tidy
+```
+
+Generate static files and start the Hugo server
+```bash
+cd /app/docs
+hugo --destination /workspace/public
+hugo server --bind 0.0.0.0 --baseURL "http://localhost:1313"
+```
