+# Deployment Values
+
+For each deployment, you need to set the environment variables and configurations.
+Here is some specific information on how to set the values.
+
+## Webapp
+
+We have several configuration possibilities just in the frontend.
+
+### Date Time
+
+In file `branding/constants/dateTime.js`.
+
+- `RELATIVE_DATETIME`
+  - `true` (default) or `false`
+- `ABSOLUT_DATETIME_FORMAT`
+  - definition see [date-fns, format](https://date-fns.org/v3.3.1/docs/format):
+    - `P`: just localized date
+    - `Pp`: just localized date and time
+
+## E-Mails
+
+You need to set environment variables to send registration and invitation information or notifications to users, for example.
+
+### SPF and DKIM
+
+More and more e-mail providers require settings for authorization and verification of e-mail senders.
+
+### SPF
+
+Sometimes it is enough to create an SPF record in your DNS.
+
+### DKIM
+
+However, if you need DKIM authorization and verification, you must set the appropriate environment variables in: `.env`, `docker-compose.yml` or Helm script `values.yaml`:
+
+```bash
+SMTP_DKIM_DOMAINNAME=<your e-mail sender domain>
+SMTP_DKIM_KEYSELECTOR=ocelot # "free" name used in DNS as selector. we recommend this
+SMTP_DKIM_PRIVATKEY="-----BEGIN RSA PRIVATE KEY-----\\n<your base64 encoded private key data>\\n-----END RSA PRIVATE KEY-----\\n"
+```
+
+You can find out how DKIM works here:
+
+<https://www.ionos.com/digitalguide/e-mail/e-mail-security/dkim-domainkeys/>
+
+To create the private and public DKIM key as DNS records with selector, see here:
+
+<https://knowledge.ondmarc.redsift.com/en/articles/2141592-generating-2048-bits-dkim-public-and-private-keys-using-openssl-on-a-mac>
+
+Information about the required PEM format can be found here:
+
+<https://docs.progress.com/bundle/datadirect-hybrid-data-pipeline-installation-46/page/PEM-file-format.html>
+
+## Neo4j Database
+
+We have several configuration options for our Neo4j database.
+
+### DBMS_DEFAULT_DATABASE – Default Database Name to be Used
+
+If you need to set the default database name in Neo4j to be used for all operations and terminal commands like our backup scripts, you must set the appropriate environment variable in: `.env`, `docker-compose.yml` or Helm script `values.yaml`:
+
+```yaml
+DBMS_DEFAULT_DATABASE: "graph.db"
+```
+
+The default value is `neo4j` if it is not set.
+
+As example see files:
+
+- `neo4j/.env.template`
+- `deployment/docker-compose.yml`
+- `deployment/configurations/stage.ocelot.social/kubernetes/values.yaml.template`
