+This works for a single deployment target. If you have multiple targets, you
+can specify url, username and password for each:
+
+```javascript
+grunt.initConfig({
+	wordpress: {
+		dev: {
+			url: "wordpress.dev",
+			username: "admin",
+			password: "admin",
+		},
+		live: {
+			url: "wordpress.com",
+			username: "admin",
+			password: "admin",
+		},
+		_default: "dev",
+		dir: "dist"
+	}
+});
+```
+
+If nothing is specified, the `_default` target is used. Override using the
+target task:
+
+	grunt target:live deploy
+
 * `url`: The URL for the WordPress install.
   Can be a full URL, e.g., `http://wordpress.dev:123/some/path`
   or as short as just the host name.
   If the protocol is `https`, then a secure connection will be used.
 * `username`: WordPress username.
 * `password`: WordPress password.
 * `dir`: Directory containing posts, taxonomies, and resources (see [Directory Structure](#directory-structure)).
+* `_default`: The default deployment target, optional.
