+# Seed Production Data Into Another Branch
+
+When you [create a Planetscale
+branch](https://planetscale.com/docs/reference/branch) off `main`, it will only
+copy over the schema. No data will be copied over to that new branch.
+
+You can copy data over from the initial branch (`main`) in two steps from the
+CLI. First, create a dump of the branch. Then restore the dump into your new
+branch.
+
+```bash
+$ pscale database dump database-name main --output ./dump
+```
+
+That creates SQL files locally in the `dump` folder with both schema and data
+statements.
+
+That folder of SQL files can then be restored into one of your branches.
+
+```bash
+$ pscale database restore-dump database-name branch-name --dir ./dump --overwrite-tables
+```
+
+The `--overwrite-tables` flag is needed because your branch's existing schema
+will conflict with the `create` schema statements in the SQL files.
+
+You can `pscale shell` into that branch and run a `select ...` statement to
+check out the data.
