+### Setting up password for demo admin user
+
+This step is a pre-requisite to installing demo configuration. You can pass the demo `admin` user password by exporting `OPENSEARCH_INITIAL_ADMIN_PASSWORD` variable with a password.
+```shell
+export OPENSEARCH_INITIAL_ADMIN_PASSWORD=<password>
+```
+
+**_Note:_** If no password is supplied, the installation will fail. The password supplied will also be tested for its strength and will be blocked if it is too simple. There is an option to skip this password validation by passing the `-t` option to the installation script. However, this should only be used for test environments.
