In RepU, open your widget, choose light or dark and left or right, then click Copy next to the embed snippet.
Open your project and find the HTML file every page shares, such as index.html or your layout template. Paste your code just before the closing </body> tag.
Push to Git or run your deploy command, then open your live site to see your Google reviews.
Check your live site in a private window, not the editor or preview. A domain-locked widget only shows on your own domain.
Check your deploy finished and you edited the file your pages actually use. If you set a Content Security Policy, allow the RepU domain.
