-* **DOCKER_REGISTRY** - corresponds to **registry**
+The Docker plugin can be used to build and publish images to the Docker registry. The following pipeline configuration uses the Docker plugin to build and publish Docker images:
-* **DOCKER_USERNAME** - corresponds to **username**
-* **DOCKER_PASSWORD** - corresponds to **password**
-* **DOCKER_EMAIL** - corresponds to **email**
-
-It is highly recommended to put the **DOCKER_USERNAME**, **DOCKER_PASSWORD**
-and **DOCKER_EMAIL** into secrets so it is not exposed to users. This can be
-done using the drone-cli.
-
-```bash
-drone secret add --image=plugins/docker \
-    octocat/hello-world DOCKER_USERNAME kevinbacon
-
-drone secret add --image=plugins/docker \
-    octocat/hello-world DOCKER_PASSWORD pa55word
-
-drone secret add --image=plugins/docker \
-    octocat/hello-world DOCKER_EMAIL kevin.bacon@mail.com
-```
-
-Then sign the YAML file after all secrets are added.
-
-```bash
-drone sign octocat/hello-world
-```
-
-See [secrets](http://readme.drone.io/0.5/usage/secrets/) for additional
-information on secrets

+# Secrets
+
+The Docker plugin supports reading credentials from the Drone secret store. This is strongly recommended instead of storing credentials in the pipeline configuration in plain text.
+
+```diff
+pipeline:
+  docker:
+    image: plugins/docker
+-   username: kevinbacon
+-   password: pa55word
+    repo: foo/bar

+
+Use the command line utility to add secrets to the store:
+
+```nohighlight
+drone secret add --image=plugins/docker \
+    octocat/hello-world DOCKER_USERNAME kevinbacon
+
+drone secret add --image=plugins/docker \
+    octocat/hello-world DOCKER_PASSWORD pa55word

+
+Don't forget to sign the Yaml after making changes:
