+# Step 7: Viewing your mdBook on GitLab Pages
+Once you've published your .gitlab-ci.yml file, or have submitted a change, you'll be able to see the status of the new deployment on both the repository main page and the CI/CD > Pipelines page.
+
+Assuming everything is setup correctly you can navigate to Settings > Pages in GitLab and you'll see the URL of the mdBook you've just created. In this case it's at https://strivinglife.gitlab.io/book-gitlab-mdbook/.
+
+This is also where you can setup a custom domain if you have and would like to use one.

+
+You can make edits to the book both locally as well as on GitLab itself by editing or creating new pages. Once you commit your changes GitLab will automatically generate an updated site.
