+#### Obtaining Your Automatically Generated DKIM DNS TXT Record
+
+[DKIM](https://en.wikipedia.org/wiki/DomainKeys_Identified_Mail) signature sending and RSA keys generation are enabled by the default Postfix image `mwader/postfix-relay` with [OpenDKIM](http://www.opendkim.org/).
+
+Run `cat ./docker-volume/opendkim/keys/*/*.txt` to display your DKIM DNS TXT Record containing the public key to configure to your domain :
+
+```bash
+$ cat ./docker-volume/opendkim/keys/*/*.txt
+
+peertube._domainkey.mydomain.tld. IN TXT ( "v=DKIM1; h=sha256; k=rsa; "
+ "p=MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEA0Dx7wLGPFVaxVQ4TGym/eF89aQ8oMxS9v5BCc26Hij91t2Ci8Fl12DHNVqZoIPGm+9tTIoDVDFEFrlPhMOZl8i4jU9pcFjjaIISaV2+qTa8uV1j3MyByogG8pu4o5Ill7zaySYFsYB++cHJ9pjbFSC42dddCYMfuVgrBsLNrvEi3dLDMjJF5l92Uu8YeswFe26PuHX3Avr261n"

+## Upgrade
+
+**Important:** Before upgrading, check you have all the `storage` fields in your [production.yaml file](https://github.com/Chocobozzz/PeerTube/blob/master/support/docker/production/config/production.yaml).
+
+Pull the latest images:
+
+```shell
+$ cd /your/peertube/directory
+$ docker-compose pull
+```
+
+Stop, delete the containers and internal volumes (to invalidate static client files shared by `peertube` and `webserver` containers):
+
+```shell
+$ docker-compose down -v
+```
+
+Rerun PeerTube:
+
+```shell
+$ docker-compose up -d
+```
+
+## Build
+
+### Production
+
+```shell
+$ git clone https://github.com/chocobozzz/PeerTube /tmp/peertube
+$ cd /tmp/peertube
+$ docker build . -f ./support/docker/production/Dockerfile.bullseye
+```
