+# Archive Only Mode
+
+Archive Only Mode is a limited version of Cyd that lets you use the features that are possible without having access to sign into an X account. If you can still sign into your account, [continue to Dashboard](./dashboard.md) instead.
+
+![Archive Only Mode](./img/archive-only-mode.png)
+
+To continue, you'll need to have already [requested your X archive](https://help.x.com/en/managing-your-account/how-to-download-your-x-archive) from X, and then downloaded it, before deleting your X account.
+
+And in order to migrate your tweets to Bluesky, you'll also need a Cyd [premium plan](../premium/intro.md).
+
+Start by clicking Continue to **Import X Archive**.
+
+![Browse for an X archive to import](./img/archive-only-import.png)
+
+From here, browse for your X archive, and then click **Start Import**.
+
+![After importand an X archive](./img/archive-only-imported.png)
+
+After the import succeeds, click Go to Dashboard. When you're in Archive Only Mode, the dashboard is limited to only features that work without a signed in X account, which right now is just Migrate to Bluesky.
+
+![Dashboard in Archive Only Mode](./img/archive-only-dashboard.png)
+
+Click **Migrate to Bluesky** to migrate your tweets to Bluesky. For more information, see [Migrate to Bluesky](./migrate-bluesky.md).
