+## Testing generated site
+
+To test the generated HTML site, you can use `html-proofer` gem.
+This Ruby gem checks and validates the jekyll generated HTML files.
+It checks a broad set of points: internal and external links existence (alerting of possible 404 errors), HTML attributes of the images and so on.
+
+To install it, It has been incorporated in the Gemfile so the previous dependency install command would have already installed it.
+
+You can run the following gem to tests the generated site.
+
+```bash 
+bundle exec jekyll build
+bundle exec htmlproofer ./_site
+```
+
+A utility script has also been included to run these checks in a CI system smoothly.
+
+```bash
+./scripts/cibuild
+```
