 Embedded Cluster stores data in the following primary locations, all of which must be writable:
 
+The default location of the data directory can be modified by the user at install time by passing the `--data-dir` flag to the `install` command.
+This directory cannot be changed after the cluster is installed.
+
+For example:
+
+```bash
+sudo ./APP_SLUG install --data-dir /data/embedded-cluster --license license.yaml --airgap-bundle APP_SLUG.airgap
+```
+Where `APP_SLUG` is the unique application slug.

 :::note
 Replicated does not support using symlinked directories for these locations. Instead, Replicated recommends bind mounts, which provide greater consistency across different applications, preserve the original directory permissions and ownership, and have less overhead compared to symlinks. For more information, see [Relocating data directories with bind mounts](https://community.replicated.com/t/relocating-data-directories-with-bind-mounts/1435) in Replicated Community.

-* Fixes several issues that caused node resets to fail. Single-node clusters are no longer drained before being reset. Resets will no longer fail with the error `unable to get installation` if the installation failed early on. And node resets will now work if bind mounts are used for `/var/lib/embedded-cluster`, `/var/lib/k0s`, and `/var/openebs`.

 * Fixes an issue where restoring did not work with S3-compatible object stores other than AWS S3.
