@@ -6,3 +6,20 @@ Before deploying metabase first time, make sure that postgres is configured:
     * you can get one via adminer or by directly connecting to container and executing `psql -U <user> -d <db>`
 
 This can be automated via https://github.com/ITISFoundation/osparc-ops-environments/issues/827

+## Extra Configuration (optional)
+
+Setting up email (manual):
+* go to admin settings
+* go to email
+* configure email using SMTP_HOST, SMTP_PASSWORD, SMTP_PORT, SMTP_PROTOCOL, SMTP_USERNAME env from config
+  - Note: `FROM NAME` shall potentially clearly indicate deployment (if we use metabase in multiple deployments this helps to avoid confusion)
+  - Note: `FROM ADDRESS` use support email (we may consider adding a separate user and mail for metabase later)
+  - Note: `REPLY-TO ADDRESS` must NOT be support email. Feel free to choose some of backenders / devops email
+
+Configuring localization (manual):
+* go to admin settings
+* go to localization
+* configure first day of the week to be `Monday`
+
+Note: later these manual steps can be automated via Metabase API calls
