+## Bug triage guidelines
+
+[Check incoming bug reports](https://github.com/puppeteer/puppeteer/issues) that do not have a `confirmed` or `needs-feedback` label:
+
+1. Make sure the issue labeled as either `bug` or `feature`.
+2. If the issue does not have a clear repro or you cannot repro, ask for the repro and set the `needs-feedback` label.
+3. Follow-up on the issues you previously asked for a feedback on (you should get a notification on GitHub when the user responds).
+4. If the user does not provide feedback, the issue will be closed by the stale bot eventually.
+5. If you are able to reproduce the issue, add the label "confirmed".
+6. If the bug is on the Chromium side, create a corresponding crbug.com issue and label the Github issue with the "upstream" label and post a link to crbug.com in the comments.
+7. If the issue is not related to either Puppeteer or Chromium, close the issue.
+8. If the issue is about missing/incorrect documentation, label it as `documentation`.
+
+Issues with PDFs:
+
+1. If the issue reproduces using the regular print dialog and/or headful, file a crbug.com against the Blink Layout component.
+2. If the issue is specific to the headless headless, file an issue on crbug.com against the headless component.
