 The above command does the following:
 
 1. register the `.ufo/output/demo-web.json` task definition to ECS untouched.
 2. deploys it to ECS by updating the service
 
-### ufo tasks build

 To regenerate a `.ufo/output/demo-web.json` definition:
 
     ufo tasks build
 
-### ufo ship
+## ufo ship
 
 The `ufo deploy` command does less than the `ufo ship` command.  Normally, it is recommended to use `ufo ship` over the `ufo deploy` command to do everything in one step:
 
 1. build the Docker image
 2. register the ECS task definition
 3. update the ECS service
 
 The `ufo ships`, `ufo ship`, `ufo deploy` command support the same options. The options are presented here again for convenience:

+## Creating mutiple environments in parallel

+If you would like to create multiple enviroments quickly in parallel, the `--no-wait` and `--build` option can help speed up the process.  Example:
+
+    ufo ship # at least once
+    for i in {1..3}; do
+      UFO_ENV_EXTRA=$i ufo deploy --no-wait --build
+    done
