 It is recommended to do most modifications in local dev environment first. Use the production environment only for making frequent live modifications like creating new blog posts and managing users.
 
-If the production database contains some confidential data like personally identifiable information of customers, you should never take a full database dump of production data for development purposes. However, if most modifications are made in local development environment and committed to git, there should be no need for production data at all. You can use the staging environment to make sure that the modifications made in local development environment work also with the current production data.

 * Deploy wordpress to the environment either by pushing some changes to the environment branch or by triggering the deployment manually: `taito deployment trigger:ENV`.
 * Immediately generate a new password for the admin user by using the WordPress admin GUI (`taito open admin:ENV`). The initial admin password is: `initial-password-change-it-on-wp-admin-immediately`. If the admin account is shared, save the new password to a shared password manager.
