 Starting with scorecard-action:v2, users can add a Scorecard Badge to their README to display the latest status of their Scorecard results. This requires setting [`publish_results: true`](https://github.com/ossf/scorecard/blob/d13ba3f3355b958d5d62edc47282a2e7ed9fa7c1/.github/workflows/scorecard-analysis.yml#L39) for the action and enabling [`id-token: write`](https://github.com/ossf/scorecard/blob/d13ba3f3355b958d5d62edc47282a2e7ed9fa7c1/.github/workflows/scorecard-analysis.yml#L22) permission for the job (needed to access GitHub OIDC token). The badge is updated on every run of scorecard-action and points to the latest result. To add a badge to your README, copy and paste the below line, and replace the {owner} and {repo} parts.
 
 ```
-[![OpenSSF Scorecard](https://api.securityscorecards.dev/projects/github.com/{owner}/{repo}/badge)](https://securityscorecards.dev/viewer/?platform=github.com&org={owner}&repo={repo})
+[![OpenSSF Scorecard](https://api.securityscorecards.dev/projects/github.com/{owner}/{repo}/badge)](https://securityscorecards.dev/viewer/?uri=github.com/{owner}/{repo})
 ```
 
 Once this badge is added, clicking on the badge will take users to the latest run result of Scorecard.
