>>> [!note] Migrated issue <!-- Drupal.org comment --> <!-- Migrated from issue #3446872. --> Reported by: [joachim](https://www.drupal.org/user/107701) >>> <p>The project page and the README send you to <a href="https://www.palantir.net/blog/jumpstart-your-drupal-9-upgrade-drupal-rector">https://www.palantir.net/blog/jumpstart-your-drupal-9-upgrade-drupal-rector</a> for documentation, but that's ancient. It also doesn't tell you anything about actually using Rector.</p> <p>It also links to <a href="https://www.palantir.net/rector">https://www.palantir.net/rector</a> which doesn't have any info at all.</p>
