-Welcome to the docker-mailserver wiki!
+## Usage
+
+#### Get v2 image
+ 
+    docker pull tvial/docker-mailserver:v2
+
+#### Create a `docker-compose.yml`
+
+Adapt this file with your FQDN.
+
+    version: '2'
+
+    services:
+      mail:
+        image: tvial/docker-mailserver:v2
+        # build: .
+        hostname: mail
+        domainname: domain.com
+        container_name: mail
+        volumes:
+        - maildata:/var/mail
+        ports:
+        - "25:25"
+        - "143:143"
+        - "587:587"
+        - "993:993"
+        volumes:
+        - ./config/:/tmp/docker-mailserver/
+        - ./opendkim/:/tmp/docker-mailserver/opendkim/
+
+    volumes:
+      maildata:
+        driver: local
+
+#### Create your mail accounts
+
+Don't forget to adapt MAIL_USER and MAIL_PASS to your needs
+
+    mkdir -p config
+    docker run --rm \
+      -e MAIL_USER=user1@domain.tld \
+      -e MAIL_PASS=mypassword \
+      -ti tvial/docker-mailserver:v2 \
+      /bin/sh -c 'echo "$MAIL_USER|$(doveadm pw -s CRAM-MD5 -u $MAIL_USER -p $MAIL_PASS)"' >> config/postfix-accounts.cf
+
+#### Generate DKIM keys 
+
+    docker run --rm \
+      -v "$(pwd)/config":/tmp/docker-mailserver \
+      -ti tvial/docker-mailserver:v2 generate-dkim-config
+
+Now the keys are generated, you can configure your DNS server by just pasting the content of `config/opedkim/keys/domain.tld/mail.txt` in your `domain.tld.hosts` zone.
+
+#### Start the container
+
+    docker-compose up -d mail
+
+You're done!
